I just tried buildconf'ing apr-util and got this
Looking for apr source in ../apr Creating include/private/apu_config.h ... Creating configure ... autoconf: Undefined macros: ***BUG in Autoconf--please report*** AC_WARNING autoconf failed
Is AC_WARNING a 2.5x macro? I can only find one occurance of it in find_apr.m4, added a few days ago.
Perhaps. *sigh* Can you try replacing AC_WARNING with AC_WARN to see if the error goes away? I'm fairly sure that it won't do the 'right' thing though. We could always suppress the warning/error if AC_WARNING isn't defined.
*sigh* -- justin
