Yes, I compiled gtk+ with xlc_r as well.

This is from config.log:
configure:5164: checking for getpwuid_r
configure:5184: xlc_r -o conftest -g -D_REENTRANT -D_THREAD_SAFE conftest.c
1>&5
configure:5209: checking whether getpwuid_r is posix like
configure:5222: xlc_r -c -g -D_REENTRANT -D_THREAD_SAFE conftest.c 1>&5
"configure", line 5218.11: 1506-098 (E) Missing argument(s).
The return code from xlc_r is 0 in this case, so configure assumes
that the test passes.
I looked inside the configure script, and this is what is going on:
==============================================================================
echo "configure:5209: checking whether getpwuid_r is posix like" >&5
# getpwuid_r(0, NULL, NULL, 0) is the signature on
# solaris, if that is not found, the prog below won't
# compile, then the posix signature is assumed as
# the default.
cat > conftest.$ac_ext <<EOF
#line 5215 "configure"
#include "confdefs.h"
#include <pwd.h>
int main() {
getpwuid_r(0, NULL, NULL, 0);
; return 0; }
EOF
==============================================================================
What is happening is, xlc_r compiles this program, and flags it with the
"(E) Missing arguments" warning. The return code from xlc_r in this case is
0, so configure assumes that the test passed, and gives the
prototype as int getpwuid_r(uid_t, struct passwd *, char *, int).
However, the POSIX prototype for this function is:
int getpwuid_r(uid_t, struct passwd *, char * , size_t , struct passwd **)
(See http://www.opengroup.org/onlinepubs/007908799/xsh/getpwuid.html)
So I think that this test is incorrect. It should test for the POSIX
version of getpwuid_r() first, not the other one. It doesn't help
that xlc_r doesn't return a proper error code. :( :(
Who maintains the configure script for gtk? I think this needs to be
fixed.
This still doesn't solve my problem of gtk programs coredumping either. :( :(
I think I'm getting a headache. :)
