Description Jens Petersen 2025-12-10 02:21:21 UTC

In the recent ELN mass rebuild, gettext failed to rebuild due to latest gcc getting more strict:

https://kojipkgs.fedoraproject.org/work/tasks/804/139870804/build.log

Like this:

In file included from /usr/include/features.h:540,
                 from /usr/include/uchar.h:26,
                 from ./uchar.h:45,
                 from c32isalnum.c:21:
./wchar.h:856:23: error: expected identifier or '(' before '_Generic'
  856 | _GL_EXTERN_C wchar_t *wmemchr (const wchar_t *__s, wchar_t __wc, size_t __n)
      |                       ^~~~~~~

and many similar errors: not sure if an #include can fix this or something?

Might be good to alert upstream too.

Reproducible: Always

Steps to Reproduce:
1. rebuild gettext in rawhide (I didn't try F43, though it has seem gcc)

Actual Results:
Fails

Expected Results:
Success

0.26 scratch build succeeds for f43 though, so maybe it is not gcc.
