I am having trouble compiling GCC for our system a Motorola SysV68k 
system. I initially got gcc to compile OK using the config for AT3b1 
but that configuration does not have a floating point co-processor, 
when I change the TARGET_DEFAULT define to account for a 68881 it produces
the following assembly code when compiling gnulib2

[...Blah..]
L%2:
	fmov.d -8(%fp),%fp1
	fdiv.d &0f4294967296,%fp1   <- our assembler does not like this !

Our assembler does not know about floating point numbers and will only
accept 0 and 0x in front of intermediate operands. 

I have tried changing the macro ASM_OUTPUT_DOUBLE_OPERAND and
ASM_OUTPUT_FLOAT_OPERAND but this has had no effect! 

Could some kind soul please give me a pointer on my next step ?
