PATCH:

[Mark Mitchell]

In a 32-bit->64-bit cross compilation environment, GCC may emit 8-byte
integer literals as signed values.  However, GAS does not handle "-"
applied to a bignum, so the assembler will fail to assemble such
files.  This patch adds support for applying "~", "-", and "!" to
bignums in GAS.

OK to apply?

	* expr.c (operand): Handle the "~", "-", and "!" operators applied
	to bignums.
