wchar.h vs. gettext-lib on AIX

[Louis Guillaume <louis%zabrico.com@localhost>]

Hi,

On AIX, pkgsrc-2019Q3. PKGSRC_COMPILER=gcc (8.3.0)

I'm having a configure problem with gettext-lib...

  checking whether putc_unlocked is declared... yes
  checking whether putchar_unlocked is declared... yes
  checking whether <wchar.h> uses 'inline' correctly... no
  configure: error: <wchar.h> cannot be used with this compiler (cc 
-I/usr/include -I/usr/include -D_THREAD_SAFE).
  This is a known interoperability problem of glibc <= 2.5 with gcc >= 
4.3 in
  C99 mode. You have four options:
    - Add the flag -fgnu89-inline to CC and reconfigure, or
    - Fix your include files, using parts of

<https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=b037a293a48718af30d706c2e18c929d0e69a621>, 
or
    - Use a gcc version older than 4.3, or
    - Don't use the flags -std=c99 or -std=gnu99.
  Configuration aborted.
  configure: error: ./configure failed for gettext-runtime
  *** Error code 1

  Stop.
  bmake[1]: stopped in /opt/pkgsrc/devel/gettext-lib
  *** Error code 1

  Stop.



So I added "USE_BUILTIN.gettext=yes" to mk.conf. Now it skips the
gettext-lib package, but now gets stuck the same way (in
gettext-runtime) for gettext-tools. What can be done?

Any help would be great. Thanks!
