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