I think this is a good idea.  I attach below the version of
config.site that I usually put inside ported packages, to be used
during the configure step.

If PATH_SEPARATOR is set to :, then you shouldn't need to set CC and
CXX because the configure script will find the compiler automatically,
provided that test -f is solved like I explain below.

The idea is not to generate test -x *instead* of test -f, but rather
make the configure script use one or the other, depending whether it
runs on Unix or on DOS/Windows.
