Thank you!
But still curious if you've been able to reproduce the problem,
and why you didn't encounter this problem beforehand.

Yes, but (you've asked) here is this situation I don't want to configure extra
deplib-prefixes
for (remember bullfreeware is listed as provider for gcc-binaries):
* bullfreeware's libiconv-1.13.1 and gettext-0.17 is installed in /opt/freeware,
* /usr/lib/libintl.a is symlinked to /opt/freeware/lib (by bullfreeware's RPM),
* /usr/lib/libiconv.a is the original AIX' one.
Now, /usr/lib/libintl.a needs /opt/freeware/lib/libiconv.a[libiconv.so.2], and
it does
contain the correct RUNPATH. But subsequent binaries linking against
/usr/lib/libintl.a
don't (necessarily) know about the need to add /opt/freeware/lib as RUNPATH, so
these
binaries break with libiconv.so.2 not being found as member of
/usr/lib/libiconv.a, because
AIX unfortunately does stop its shared-library search at the first archive
filename found.
This also is the main reason for my filename-based-shared-library-versioning
thing.
While this topic is related, it has different reasoning - but the result does
work:
