Hmmm, the problem is, that the gcc is strongly oriented on gas and
	a) gas allows numbers to be given in several representations like
	   hexadezimal with prefix "0x" or binary ("b"??).
	b) "#" is a comment symbol for gas (ignored since part of the output
	    of cpp i think) and is part of the signs "#APP" and "#NOAPP"
		which enclose inline-assembler
	c) "$" is the prefix for an immediate operand in gas.

Ahh, now I found at least something:
in gcc/config/<your arch>/*.h
You can configure the output for 
	IMMEDIATE_PREFIX 
	REGISTER_PREFIX

At least you can shift it somewhat to your favor. Another possibility to
prepare the gcc output for a different assembler (which I think to be what
you want) would be to fix the assembler code using "sed".

Regards,
	Stefan.
