A common problem is that, on some systems, gcc's preprocessor will
define one set of defines for straight C, but then for Objective C
there will be a slight difference, say, that __STDC__ is different.
Then that propagates to the standard headers which sets several
#defines differently, like the preprocessor variables you're talking
about, and that in turns makes everything look weird.  So you might
make a simple `hello world' program in C and Objective C and compare
the preprocessor settings when you compile them with "gcc -E hello.c"
and "gcc -E hello.m".  If you identify a difference, say that FOO and
BAR were missing in the latter case, you can then do a `configure'
with explicit changes, e.g.

   CC="gcc -DFOO -DBAR" ./configure
