I've checked in some changes to the LIBDFP branch. The major change in this commit is completely rewriting printf_dfp to properly display decimal types for the %f, %e, and %g conversions, based on draft TR24732. When a precision is not specified, the number of significant digits inherent in the decimal type is used. The Makefile also uses a new sysd-rules-patterns variable introduced by Roland recently, though the base libc makefile support isn't checked in -- this will appear after merging EGLIBC trunk soon. Other minor changes are detailed below.
* libc/configure.in: Changed --enable-decimal-float option to use
AC_ARG_ENABLE instead of AC_ARG_WITH.
* libc/stdio-common/vfprintf.c: Fixed tabs on line continuations
* libc/dfp/Makeconfig: New file. Uses new sysd-rules-patterns
variable.
* libc/dfp/sysdeps/powerpc/numdigits.h: New file.
* libc/dfp/sysdeps/powerpc/dpd-private.h: Removed tables.

dpd-private.h to here.
