VAX VMS C / UNIX C Compatibility -- Need Info

[Robert Perlberg]

Is the VAX VMS C-compiler compatible with UNIX?  That is, can I take
C files that compiled under UNIX and compile them under VMS with no
changes other than the shell commands inside of system() calls? A guy
in my office says that to hope for this is naive at best, but I thought
that this ability was supposed to be a feature of C.

Another thing I'm looking for under VMS is the ability to load both
C and FORTRAN object files into one executable. Does anyone know if
this works?
