Hi Alex,

     exactly what issues have you had with the Plan 9 compiler and what are
the changes to VMMaker you had to make?  You may have already written a
message on this.  Of so, can you send me a link to it.  Otherwise it will
help me integrating to know.  The Cog VMMaker's translation-to-C subsystem
is quite different from the trunk VMMaker and straight-forward integration
is probably not possible.
