Hi Scott,

sorry for not fixing this sooner - yes it should be very easy to
support.  Slightly surprised it fails - will fix it soon!  Incidentally
I'm currently fixing the cyclic array -> pointer -> array declaration
bug you emailed me with 2..3 weeks ago.  I've rewritten
M2GCCDeclare.mod in the process and I hope to commit the changes in the
next couple of days,

regards,
Gaius
