vms update (trunk only)

vms update (trunk only)

     I hadn't tried the build script vmsbuild.com in a long time....
vmsbuild.com wasn't compiling src/sys.c;
vmsbuild.com and Makefile.src+Makefile.utl had some linking discrepancies;
Makefile.top, Makefile.dat, Makefile.doc - replace old SCCS id/date/rev
  comment with current cvs one (done for .src & .utl a month or so back);
config1.h - running DEC C in VAX C compatability mode to test linking
  yielded a diagnostic about signed in the schar typedef for every file.
