[Patches] Clean up some cross-localedef code
- To: <patches@xxxxxxxxxx>
- Subject: [Patches] Clean up some cross-localedef code
- From: "Joseph S. Myers" <joseph@xxxxxxxxxxxxxxxx>
- Date: Thu, 5 Sep 2013 23:35:22 +0000
I've applied this patch to clean up some of the cross-localedef code in
EGLIBC's localedef to align more closely with the glibc code, as modified
by the first-stage patch I sent to make glibc use the better interfaces
internally in localedef. Some fixes are for coding standards, some for
compiler warnings found while preparing that patch for glibc; some revert
changes once made to avoid C99 features in localedef (there's really no
point in trying to make it usable by old host compilers).
This should facilitate merges after some version of that patch is in
glibc, as well as making it easier to see what pieces remain to merge.
As a reminder, I do not plan to merge any sort of separate build system
for cross-localedef or support for building localedef for a system other
than that for which glibc is being built; I only plan to merge the changes
to allow localedef built with glibc for one system using glibc to be used
to generate locales for another system using glibc. If you wish to
continue to use a cross-localedef binary after EGLIBC is phased out, other
than through running a localedef binary from a normal glibc build with the
libc from that build, you should plan to work on implementing such
features for glibc in the near future.
