I've had to hack Simgear's configure.ac quite a bit [for Mac OS X],
using the Plib one as a reference.
The basic construct (a big switch statement based on the target
type) is nice, I think, since it moves lots of IRIX / cygwin / OS-X
specialties out of the way cleanly. Much more re-factoring of the
current tests in configure is possible if people are able to test.
