libgomp breaks bootstrap on NetBSD because of
   cc1: warnings being treated as errors
   ../../../gcc/libgomp/env.c: In function 'parse_stacksize':
   ../../../gcc/libgomp/env.c:207: error: array subscript has type 'char'
   ../../../gcc/libgomp/env.c: In function 'parse_spincount':
   ../../../gcc/libgomp/env.c:276: error: array subscript has type 'char'

I have committed the attached patch under the obvious rule.

Bootstrapped and tested on x86_64-unknown-netbsd4.0 and
i386-unknown-netbsdelf3.1.

 	* env.c (parse_stacksize): Add cast to avoid warning.
 	(parse_spincount): Likewise.
