IMHO, what would be cool is to allow the user to pass the SDK in as
some sort of configure flag or maybe a shell variable, something like:
./configure <flags> MACOSX_SDK=/my/path/to/SDK
This, along with the addition of the -arch i386 -arch ppc flags would
be enough to enable someone to write a script to create a Panther-
compatible Universal build. Which I'm pretty sure someone will do
sooner or later. :-)
