What did you change to get it to stage 2? My trial run is dying after 
building the stage1 compiler...

Some changes I've made: on gcc/pfe/pfe-mem.c, I had to undefine 
APPLE_MAC_OS_X_IMPLEMENTATION, so it would not try to include Mach headers. 
Also, I ended up passing -UTARGET_MACHO on CFLAGS (solves a bunch of files 
trying to include Mach-O support), and commenting a lot of APPLE_LOCAL 
changes only applicable to Darwin (for example, a flag about building M68K 
stuff). Small stuff, mostly; no changes other than commenting code that 
doesn't compile.

However, on the first file that it tries to build with xgcc, it dies with 
an Assembler error message. Does it require Apple's version of as?

I'm very glad to hear that... I hope I can be compiling ObjC++ code on my 
Linux box soon!
