	Recognizing the target name is not sufficient.  Merging in the
"config" files themselves are a start, but they probably are not
compatible with the internal interface changes between egcs-1.1.2,
gcc-2.95.2, and the current development snapshots.

	Also, my understanding is that Apple made other pervasive changes
in the compiler to support Mach-O file format and other NeXT-isms.  Apple
is working to make those changes more modular so that they can be
contributed back to the mainline GCC development sources.
