Unreviewed patches: avoid warnings

[Jan van Male#84776]

Hi all,

These two patches have been unreviewed:
http://gcc.gnu.org/ml/gcc-patches/2001-08/msg00445.html
http://gcc.gnu.org/ml/gcc-patches/2001-08/msg00677.html

The last patch will no longer apply cleanly: the change to expmed.c now 
gives a conflict.  In a recent change, INTVAL was cast to `unsigned int'.  
I believe this is not safe since INTVAL is a HOST_WIDE_INT.  The attached 
patch fixes this.  Bootstrapped i686-pc-linux-gnu.

ChangeLog:
2001-08-24  Jan van Male  <jan.vanmale@fenk.wau.nl>

	* expmed.c (expand_shift): Cast INTVAL to unsigned HOST_WIDE_INT instead 
	of unsigned int.
