Hm? The GNU stuff is portable across a lot of platforms, not least
because of using autoconf.

The problem with the ifdefs is that the person writing a particular
line of code rarely has access to the dozen or more platforms where it
might need to run on. So he does not necessarily know what to put in
Autoconf might not be the prettiest system around, but as far as I can
see, it does its job.
