CFLAGS="-Wall -g -m32 -ansi" You don't need -m32, but you definitely shouldn't set -ansi globally. Please fix that and try again.
Those CFLAGS come from my bash environment variable $CFLAGS. I agree I should not force -ansi on you, but IMHO neither should you be forcing me to use a specific CFLAGS outside of portage. Moreover, all other packages seem to have successfully overridden my environment. My /etc/make.conf contains CFLAGS="-O2 -march=pentium4 -fomit-frame-pointer -pipe -mfpmath=sse -msse2 -mmmx" I have to wonder why the ebuild didn't use that; it's there for portage's sake, after all. I have to thank you for the quick reply, though, since it gave me a simple workaround. I recompiled with "CFLAGS= emerge libao" and all was well. The environment variable is very useful to me as it is in other work, so I'd like to keep it, please.
Kevin, Portage is designed so that your environment overrides configuration files. If you'd rather keep those CFLAGS in your environment, you might want to just ensure that they're only set for your regular user (where you likely do development) and not for root. Alternately, use sudo, which resets the environment by default. It's unlikely that all other packages overrode your environment CFLAGS; rather, they probably were valid C89 and compiled with -ansi.
This isn't a bug, this is purposeful design of the way portage works.
