+$! This file sets things up to build gas on a VMS system to generate object
+$! files for a VMS system.  We do not use the configure script, since we
+$! do not have /bin/sh to execute it.
+$!
+$! If you are running this file, then obviously the host is vax-dec-vms.
+$! [That's no longer obvious, but there's not much we can do about alpha yet.]
