Apologies in advance if this is a FAQ, but i haven't seemed to locate
FAQ/Answers for either gnu.gcc.help or comp.sys.intel, yet.

My question has 2 parts:

1. VANILLA question: 

	HOW does one create a cross-compiler from machine a to machine b, in
what (i hope :-) is the simplest possible case, i.e. i'm happy to keep using
the EXISTING cross-assembler and cross-linker, but wish merely to invoke GCC
for the compiler phases which turn C-source into Assembler?

2. Non-Vanilla question: (pending the answer to question #1)

	SPECIFICALLY for
			--==> sparc <==--
cross-compilation of object/executable code to be run on the 
			--==> i860  <==--
what must be done that is not in the gcc distributed documentation (i have
version 1.39 from prep)?

Once again, just for clarity:

I am not even trying to replace the existing assembler/linker, just the
	{C source} --==> {i860 assembler}
phase (although admittedly, i wouldn't mind finding out how to bring up gas
and/or gnu ld for the later compilation phases as well, if I succeed with
getting gcc to work for the "C2assembler" part).

Thanks very much
