dovecot - Sep 2010 - configure error

Hi all,

on my system ("AIX 6.1" with "xlc -q64") the
"configure" script for
"dovecot-2.0.2" breaks with:

   checking whether fd passing works... no
   configure: error: fd passing is required for Dovecot to work

in config.log:

   configure:19524: ./conftest
   configure:19524: $? = 1
   configure: program exited with status 1


It seems, that the last changes in "src/lib/fdpass.c" are the reason.

Using the old version (from "src/lib/fdpass.c") make no trouble.

The compiler error message would have been useful to know. What if you
change these to:

*fd = *((int *)cmsg_data);

Does that make xlc happy?

This is also now fixed:
http://hg.dovecot.org/dovecot-2.0/rev/bdf922d26534

I didn't realize it was a runtime error instead of compile error. Still
strange though.. Either there's something I don't understand about it or
it's a compiler bug.
