Changing GAS for ARM to accept semicolon as a comment character ?

This would silently break any file that relied on it.  In particular, I 
believe ';' is the only supported statement separator, so I think removing 
it would make #define macros in assembly files that need to generate more 
than one statement impossible.

It would certainly break NetBSD's support code.
