Currently when building unwind-dw2.c for powerpc64 I see

In file included from ../../../libgcc/unwind-dw2.c:376:0:
./md-unwind-support.h: In function 'frob_update_context':
./md-unwind-support.h:371:8: warning: passing argument 3 of 
'_Unwind_SetGRPtr' makes pointer from integer without a cast [enabled by default]
../../../libgcc/unwind-dw2.c:281:1: note: expected 'void *' but argument 
is of type '_Unwind_Word'

looking at other places we cast such arguments to void *.

Ok?

Thanks,
Richard.

	* config/rs6000/linux-unwind.h (frob_update_context): Properly
	cast the third argument of _Unwind_SetGRPtr to void *.
