This is exactly the problem which prompted my first posting.  I have some
code which I want to be portable across many systems - VMS being one of them.
So, the code looks like this:

	#ifdef VMS
	#include file
	#endif

where '#include file' is valid Vax-C syntax ('file' is the name of a module
in a standard text library).  The problem is that the 3B2 chokes on that
line, even though VMS is NOT defined.  Oh well...
