Thanks for the idea, but I was able to bypass libc;
I was going to email the list with my solution as
soon as I ironed out some kind of incompatibility
I'm getting in object code between C++ compilers
(of the same version). Though I haven't figured
it out, this is the simple solution derived from
http://www.osdev.org/wiki/GCC_Cross-Compiler

	tar xjf binutils-2.17.tar.bz2
	mv binutils-2.17 src
	
	mkdir build
	cd build
	
	export PREFIX=/usr/local/xgcc
	export TARGET=i686-elf
	
	../src/configure --target=$TARGET --prefix=$PREFIX --disable-nls
	
	make
	sudo make install
	
	--------------------------------
	
	tar xjf gcc-core-4.1.2.tar.bz2 && tar xjf gcc-g++-4.1.2.tar.bz2
	mv gcc-4.1.2 src
	
	mkdir build
	cd build
	
	export PATH=$PATH:$PREFIX/bin
	
	../src/configure --target=$TARGET --prefix=$PREFIX --disable-nls -- 
enable-languages=c,c++ --without-headers
	
	MACOSX_DEPLOYMENT_TARGET=10.4 make all-gcc
	sudo make install-gcc

That MACOSX_DEPLOYMENT_TARGET=10.4 is necessary on Mac OS X 10.5

In any case, I wish that the configuration process/switches were cleaned
up and documented more.

Sincerely,
