$!
$! Makefile.com - builds GNU Make for VMS
$!
$! P1 is non-empty if you want to link with the VAXCRTL library instead
$! of the shareable executable
$! P2 = DEBUG will build an image with debug information
$! P3 = WALL will enable all warning messages (some are suppressed since
$! one macro intentionally causes an error condition)
$!
$! In case of problems with the install you might contact me at
$! zinser@decus.de (preferred) or zinser@sysdev.deutsche-boerse.com
$
$! hb
$! But don't ask Martin Zinser about the lines, I added/changed.
$! In case of an error do some cleanup
$ on error then $ goto cleanup
$! in case somebody set up her/his own symbol for cc
$ set symbol/scope=(nolocal,noglobal)
