# The problem that I'm trying to solve here by specifying gcc-3.3 and gcc2
# in the search list ahead of the other stuff is that gcc-3.1 on Mac OS X
# does not work for some of the pdf extractor code. Now, it would seem
# that we could have a conditional on $host_os that puts just the right
# amount of crazyness into the checks only on the Mac. Unfortunately, this
# will not work, because (according to some mailing lists and painful
# personal experiences) AC_PROG_CXX does not work inside of conditionals.
# So, instead, we do this crazyness globally. The list of compilers that
# you see below is taken right out of the autoconf (version 2.57) sources,
# so it should not impede our portability.
