* configure: Regenerated.
* Makefile.in: Remove appending of cc_msize to CFLAGS.
* configure.ac: Remove cc_msize and cc_mzarch and accompanying
AC_SUBST. The preferred method is to require the user to pass
-m[31|32|64] in CFLAGS as an env variable when configure is invoked.
* README.user: New file.
* README.developer: Updated to direct user to pass -m[31|32|64] in
CFLAGS and to always use --build and --host values that align with the
-m values.

-pass the following switches:
+Environment Variables
+
+CC
+ Select your compiler.
+
+CFLAGS="-m64 -O2 -g"
+ Since the default bitness of the compiler's generated binaries varies

+ -m[31|32|64] flags be passed.
+
+ Some System Z machines require the -mzarch flag, e.g.
+ CFLAGS="-m31 -mzarch -O2 -g"
+
+ These should accompany sympathetic --build and --host switches
+ described below, e.g.
+
+ powerpc-linux-gnu for -m32
+ powerpc64-linux-gnu for -m64
+
+ASFLAGS
+ Libdfp's Makefile.in will pull -g or -m[31|32|64] into ASFLAGS if it is
+ specified in CFLAGS. If you need anything else, pass it in here and
+ it'll be added.
+
+Libdfp's default configure will be based on whatever bitness the user
+environment is.

+---------------------------------------------------------------------------
+1. Introduction
+
+The "Decimal Floating Point C Library" is an implementation of ISO/IEC
+Technical report "ISO/IEC TR 24732" which describes the C-Language library
+routines necessary to provide the C library runtime support for decimal
+floating point data types introduced in IEEE 754-2008, namely _Decimal32,
+_Decimal64, and _Decimal128.
+
+---------------------------------------------------------------------------
+1.1. ISO/IEC TR 24732
+
+The latest description of ISO/IEC TR 24732 at the time of this writing can
+be found here:
+
+ http://www.open-std.org/JTC1/SC22/wg14/www/docs/n1312.pdf
+
+A rationale can be found here:
+
+ http://www.open-std.org/JTC1/SC22/wg14/www/docs/n1242.pdf
+
+---------------------------------------------------------------------------
+1.2. IEEE754-2008 (DPD & BID Encodings)
+
+IEEE 754-2008 defines two different encodings for the decimal floating
+point data types. These are DPD and BID.
+
+ DPD (Densely Packed Decimal) - IBM sponsored encoding (implemented
+ in hardware).
+
+ BID (Binary Integer Decimal) - Intel sponsored encoding.
+
+Both encodings can be investigated in the draft IEEE754r:
+
+ http://754r.ucbtest.org/drafts/archive/2006-10-04.pdf
+
+---------------------------------------------------------------------------
+1.3. Backends (libdecnumber & libbid)
+
+Libdfp can make use of two backend libraries for software emulation. These
+are "libdecnumber" and "libbid".
+
+For the most part, a user of libdfp should not have to be concerned with
+the libdfp backends.
+
+The user's interface is that defined by ISO/IEC TR 24732, i.e. the Decimal
+Floating Point addition to the C Language specification.
+
+Currently Libdfp only supports the libdecnumber backend.
+
+---------------------------------------------------------------------------
+2. Availability
+
+Libdfp attempts to provide an encoding agnostic API to users based upon the
+_Decimal32, _Decimal64, and _Decimal128 data-types and the proposed C-Language
+extension for Decimal Floating Point Types.
+
+---------------------------------------------------------------------------
+3. Compliance With ISO/IEC TR 24732
+
+This section covers issues related to compliance with ISO/IEC TR 24732.
+
+---------------------------------------------------------------------------
+3.1 __STDC_WANT_DEC_FP__
+
+The standard ISO/IEC TR 24732 indicates that programs that wish to use
+Decimal Floating Point should define the following macro:
+
+ __STDC_WANT_DEC_FP__
+
+There is no set value for this macro.
+
+Simply passing -D__STDC_WANT_DEC_FP__ on compilation, or defining it in your
+program should suffice:
+
+#define __STDC_WANT_DEC_FP__
+
+This macro is REQUIRED when including dfp/math.h dfp/fenv.h, etc to pick
+up the DFP function prototypes and data types defined in these headers.
+
+---------------------------------------------------------------------------
+3.2 GNU99 Compatibility
+
+GNU99 compatibility is required to pick up some DFP prototypes that are
+similar to the binary floating point prototypes guarded in <math.h> by
+__USE_ISOC99 and others. It will define __USE_ISOC99.
+
+Use the following compilation flag: -std=gnu99
+
+NOTE: -std=gnu99 IS NOT THE SAME AS __USE_ISOC99 though -std=gnu99 DOES
+DEFINE __USE_ISOC99! Additionally, simply using -std=c99 isn't enough!
+
+NOTE: If you forget to use -std=gnu99 you may notice that you will get very
+screwy results when you call dfp math functions. If the compiler can't find
+the prototypes (due to missing defines) it will attempt to create a default
+prototype which will have the incorrect return type.
+
+Compile with -Wall to pick up undefined prototype warnings.
+
+---------------------------------------------------------------------------
+3.3 scanf Support
+
+Libdfp does not, and will not comply with the TR 24732 requirement for the
+addition of scanf in support of decimal floating point data types. The
+strtod[32|64|128] functions can be used for the same purpose without the
+implications of scanf.
+
+---------------------------------------------------------------------------
+3.4 printf Support
+
+Libdfp supports the addition of the printf format codes indicated by TR
+24732. GLIBC proper owns the printf implementation. Libdfp utilizes the
+printf-hooks mechanism provided by GLIBC to register support of the DFP
+format codes.
+
+The fully functional printf-hooks mechanism was debuted in GLIBC 2.10.
+
+Libdfp handles the registration of printf-hooks with GLIBC but a user must
+ask Libdfp to do so if he/she wishes to use any printf variants with
+Decimal Floating Point types by executing the following function prior to
+execution of printf with DFP types:
+
+ #include <dfp.h>
+ register_printf_dfp();
+ printf
+
+After registration of the DFP printf-hooks printf will recognize the following
+length modifiers:
+
+ %H - for _Decimal32
+ %D - for _Decimal64
+ %DD - for _Decimal128
+---------------------------------------------------------------------------
+4. Dependencies
+
+---------------------------------------------------------------------------
+4.1 GNU/Linux OS
+
+Libdfp is only enabled to work on the GNU/Linux OS.
+
+---------------------------------------------------------------------------
+4.2 GLIBC Minimum Version
+
+Libdfp version 1.0.0 relies upon a minimum GLIBC 2.10 for printf-hooks
+support. The libdfp configure stage will check the libc that it is linked
+against for the printf-hook support and will warn if it is not found.
+
+---------------------------------------------------------------------------
+4.3 GCC With --enable-decimal-float Support
+
+There's a dependency on a version of GCC which supports Decimal Floating
+Point. Use the following to determine if your compiler supports it:
+
+ gcc -v 2>&1 | grep "\-\-enable\-decimal\-float"
+
+If decimal floating point support is not available in your compiler the
+libdfp configure stage will fail with a warning.
+
+---------------------------------------------------------------------------
+5. _Decimal* Data Types
+
+The Decimal Floating Point data types are as follows:
+
+ _Decimal32
+ _Decimal64
+ _Decimal128
+
+The floating point suffix for DFP constants follows:
+
+ 'DF' for _Decimal32, e.g. _Decimal32 d32 = 1.045DF;
+ 'DD' for _Decimal64, e.g. _Decimal64 d64 = 1.4738273DD;
+ 'DL' for _Decimal128, e.g. _Decimal128 d128 = 1.0823382394823945DL;
+
+NOTE: Assigning a naked constant to a DFP variable will actually be
+performing a binary to decimal conversion and, depending on the precision,
+can assign an incorrect number. Always use the decimal floating point
+suffix!
+
+---------------------------------------------------------------------------
+6. Compile and Link
+
+A compilation and link for a DFP program will look like the following:
+
+ $(CC) -Wall test_dfp.c -o test_dfp -D__STDC_WANT_DEC_FP__ -std=gnu99 -ldfp
+
+---------------------------------------------------------------------------
+7. Unsupported/Non-Standard Additions
+
+Libdfp provides a non-standard method for output of the decoded Densely
+Packed Decimal representation using the decoded[32|64|128]() functions. The
+output format is:
+
+ [sign][MSD],[decoded-declet-1],...,[decoded-declet-n][E][+|-][decoded exponent]
+
+Examples:
+
+ +0,000,000E+0 = decoded32(0DF)
+ +0,000,000,000,001,000E-1 = decoded64(100.0DD)
+ -0,000,000,000,000,000,000,000,000,039,654,003E-3 = decoded128(-39654.003DL)
+ +9,876,543E+22 = decoded32(9.876543E+28DF)
+
+WARNING: Do NOT rely on these methods for user space code. They're only
+provided for toolchain development debug support.
+
+A header file providing the prototype for these functions is not provided by
+the Advance Toolchain to discourage you from using them. If you MUST use them
+define the following prototypes in your program:
+
+ /* char * should ref a 14 byte char array, +0,000,000E+0\0 */
+ extern char * decoded32 (_Decimal32, char*);
+ /* char * should ref a 26 byte char array, +0,000,000,000,000,000E+0\0 */
+ extern char * decoded64 (_Decimal64, char*);
+ /* char * should ref a 50 byte char array, * +0,000,000,000,000,000,000,000,000,000,000,000E+0\0 */
+ extern char * decoded128 (_Decimal128, char*);
