optimization/7001: gcc-3.1 and 3.04 on x86 generate bad memset code

[Adam J. Richter]

I applied the patch, and xterm and netscape seems to be working
again.  Thank you very much.

I searched the gnats database for "memset" before submitting
my bug report.  I guess I should have searched more thoroughly.

I do not see a way from the gnatsweb page that I can close
my bug report (7001) or indicate that it is a duplicate of 6703,
but you're welcome to point me to instructions for that or to
close the bug yourself.

Thanks for the quick reply and the patch.
