Re: GSIMap and gcc 2.95

[Riccardo Mottola]

Hi,

with the current setup this causes an error and stops compilation, even 
if it looks harmless.

casting to (void *) seems to solve the problem, I changed both the _KYE 
and the _VAL macros.

I have tested this on GCC4 and x86 and commited it, thanks.

I'll resume sparc/gcc2.95 testing ASAP.
