VAX VMS C / UNIX C Compatibility -- Need Info

No.  You will likely need to run some sed scripts over things to take
into account different # include statement syntax.  DEC-C also does not
know about the void type.  These are mostly annoyances, not show
stoppers.

Yes.  This is a BIG selling point.  Almost all of DEC's language
products use a compatible calling convention and object format.
