Hi,

the patch below adds a compile time warning which is present on the 
32-bit target but not on the 64-bit target.

I think it is missing since the beginning.

The patches 'fixes' the gcc.dg/20021014-1.c test case on x86_64-freebsd.

Ok for trunk and 4.6?

Thanks,
Andreas

	* config/i386/freebsd64.h (LINK_SPEC): Emit the same warning as the
	32-bit target does.
