Hi David,

The problem is this configure test from gettext.m4
checking for GNU gettext in libintl... no
It should say
checking for GNU gettext in libintl... yes
I reproduce it with simple hello-world package, outside GCC.
It tests whether a program that uses gettext() can be linked with
-lintl -liconv
But now, on AIX, it needs to test whether such a program can be linked with
-lintl -liconv -lpthread

It requires a change, effectively to do as if HAVE_PTHREAD_API is undefined
if --enable-threads=isoc was provided.
I can prepare a new gettext release that has both issues fixed:
- gettext.m4 that fixes the configure test and sets the variable LIBINTL
to "-Lsome/libdir -lintl -liconv -lpthread",
- mbrtowc.o and setlocale*.o that use mtx_* locks instead of pthread_*
mutexes when requested.
But you then need to make up your mind w.r.t. what I wrote in the earlier
mail.
* GCC can pass --enable-threads=isoc, to avoid the libpthread dependency
on AIX ≥ 7.2.
* Or GCC can (continue to?) use the variable LIBINTL. This will work on
AIX 7.1 as well but the programs will then be linked against libpthread.
One additional library.
$ ldd gcc
/opt/freeware/bin/gcc needs:
/usr/lib/libc.a(shr.o)
/opt/freeware/lib/libiconv.a(libiconv.so.2)
/usr/lib/libc.a(_shr.o)
/unix
/usr/lib/libcrypt.a(shr.o)
/opt/freeware/lib/libgcc_s.a(shr.o)
libpthread.a will be added to this list.
ibm-clang links against libpthread.a as well:
$ ldd /opt/IBM/openxlC/17.1.1/bin/.ibm-clang.orig
/opt/IBM/openxlC/17.1.1/bin/.ibm-clang.orig needs:
