It seems I found a bug in gpc. If I try compiling a Pascal program (see the attachment), something like this appears:

/tmp/cc4P4VfS.s: Assembler messages: /tmp/cc4P4VfS.s:17865: Error: suffix or operands invalid for `mov'

I use Debian GNU/Linux 2.2 and gpc version 19991030 on Intel PC.

I can't reproduce the problem on my system, neither on a Debian 2.2 I have access to. So it might have been fixed in the more recent versions of GPC, so you might want to upgrade (you can get them as sources, but they're easy to compile under Linux).
