There's no equivalent to features.h... And while this includes
a few repeats:
bash-3.2$ find /usr/include/ -name \*.h|xargs fgrep -h \#ifdef|sort|uniq|wc -l

I missed the suggestion altogether. Sounds like the right thing
to do.

The #ifdef _ALL_SOURCE in netdb.h comes right after the #endif of
#ifdef _XOPEN_SOURCE_EXTENDED. So all doesn't really mean all,
just kinda sorta maybe some.
Yeah, AIX is a joy. And thanks to DARPA and the DOE, it ain't
going away. The following seems to work for me on Solaris 5.8
and AIX 5.3.
