The same here:
- AIX 5.2,
- xlC 6,
- uwimap and qpopper in production and
- dovecot for testing.

No, I'm not using AIS FS quotas nor I've any experience with that, sorry

You can, but bash is backwards compatible to sh. I'm usually using bash
because of it's performance. You may try this:

# CONFIG_SHELL=bash time bash ./configure

# time ./configure

I'm using xlc and dovecot-cc depends on it. I've haven't use gcc on AIX
for years :-)
So in my opinion a common problem with xlc (or better xlc and AIX) is
the shared object handling. Libtool seems to fix most of the problems.
I've mentioned this in
