	PowerPC is an architecture, not a specific GCC target.  Without
specifying the OS and file format, it is difficult to comment on your
message. 

	The syntax for emitting 64-bit constants is specified by the
definition of DOUBLE_INT_ASM_OP in the GCC configuration for the
particular PowerPC sub-target.
