That reminds me that I've got various small repairs and changes to merge in.
Possibly the best way will be to point to a test version in an announcement
here, and
then people can check that they work for them, so nothing breaks
unexpectedly on
recompilation.

One potential big future change (not yet made) is to switch to strictly
ANSI rules for unsigned+signed
values meeting in "the usual arithmetic conversions". The rules are
horrible, but it's one of the
few ways in which the compiler implements something that's neither an
extension nor a restriction
compared to the standard. You'll never miss most of the others. One
approach there is to have
the compiler consider the type under both systems and warn if the
difference might cause trouble
(typically in comparisons, but there might be other cases). Most of the
Plan 9 source has
been compiled under the ANSI regime in the form of Plan 9 Ports, so I'd
expect that most of the
tricky cases have already been fixed.
