Actually, this is a target issue, and thus is not suitable for autoconf
(it happens to work in your case because host == target when doing a native
build).

So, the right thing to do is determine what systems need it and put that
info in the target .h files statically.

Though as you mention, I'd like to know how Pilippe got this change to work
on his machine.  Maybe it's due to a different version of the OS.
