Stephen Webb's staging headers patch

[David Edelsohn]

David> That would avoid multilibbed target includes as well.

Ben> Excellent.

	How's this change?  I think it it should be correct for the RH
16-bit targets as well, but I'm not sure how GCC C types are defined for
16-bit targets.  This probably is not correct for targets with unusual
word sizes, but it's better than the current situation.

Thanks, David


	* include/bits/limits_generic.h (int): Set digits and digits10
	appropriately for word size.
	(unsigned int,long,unsigned long): Likewise.
