$! Build the GNU C compiler on VMS.
$!
$! CAUTION: If you want to link gcc-cc1 to the sharable image library
$! VAXCRTL, see the notes in gcc.texinfo (or INSTALL) first.
$! Usage:
$! $ @make-cc1.com [host-compiler] [various]
$!
$! Build the GNU "C" compiler on VMS
$! where [host-compiler] is one of "GNUC", "VAXC", "DECC";
$! default when none specified is "GNUC",
$! and where [various] is one or more of "CC1", "CC1PLUS",
$! "CC1OBJ", "OBJCLIB", "INDEPENDENT", "BC", "ALL", "LINK", "DEBUG".
$! "CC1" (C compiler) is the default; of the others, only
$! "CC1PLUS" (C++ compiler), "CC1OBJ" (Objective-C compiler),
$! and "OBJCLIB" (Objective-C run-time library) are of interest
$! for normal installation.
$! If both [host-compiler] and other option(s) are specified,
$! the host compiler argument must come first.
$!
$! Note: to build with DEC's VAX C compiler, uncomment the 2nd CC, CFLAGS,
$! and LIBS alternatives, and also execute the following command:
$! DEFINE SYS SYS$LIBRARY:
$! After a successful build, restore those items and rebuild with gcc.
