Autoconf caters to a wider variety of projects than gnulib, so in some
cases it has to be more conservative than gnulib does.  It still
supports pre-ANSI C, for example, but the current GNU standards don't
require that and gnulib doesn't support it.

I prefer "#if HAVE_FOO", as it's easier to read, and I'd rather not
convert everything in sight to "#ifdef HAVE_FOO".  I'm currently
grudgingly willing to make an exception for Autoconf, to encourage its
use among pickier projects.  (But if this turns into too much work,
I'll stop being willing ....)
