binutils/stabs.c fixes

[Mark E.]

Hi guys,
I was reading through archive and noticed there was another bug in 
binutils/stabs.c that needed to be fixed. This patch incorporates Ian's 
suggested fix. But since gcc has no way to generate N_WARNING stabs it seems, 
the patch should probably first be tested by the person who reported the bug.

Thanks,
Mark
