I just discovered that the AC_PROG_CC macro can only be used once within a
configure script. Its definition includes "m4_expand_once()". We have *two*
invocations: one in apr_hints.m4, and one in the main configure.in.
The hints one is fully expanded, and the main one is partial. However, the
hints invocation is in the AIX *conditional*. Therefore, a full check of the
compiler characters *never* happens. That completely bombs out a bunch of
other tests, particularly the libtool stuff.
I've fixed the stuff and am testing now. Watch for a checkin later.
I'm also seeing some caching issues. It doesn't seem to reuse config.cache
for some reason. Haven't looked into that one.
Cheers,
