[M3devel] CM3 problems

[Mika Nystrom]

I ran upgrade.sh before compiling, so everything should be up to date.

I'd be happy to give you the code (yes it's mine) but I'm not sure
how many libraries it depends on.

Same thing happens with optimization (-O2).

I copied the derived directory (after running cm3 -x -keep) to 

http://rover.gcapltd.com/~mika/ximport-bug-FreeBSD4/

in case anyone wants to peek at it.  I also put Main.m3 in there
so you can see what's going on.  Nested procedures... but nothing
that looks too weird to me.
