Really?  Which compiler do you use?  The VAX11 C (trademark of DEC, I'm
sure) compiler (1) understands <stdio.h> as well as other nifty things
like <signal.h> and <setjmp.h> that one would expect to be UNIX (TM)
dependant.  Furthermore, externals do NOT need to be initialized.

My experience has been that UNIX code ports to VMS with little trouble,
unless (1) you wire file names, or (2) use lots of process/job control
stuff that VMS does not support.
