$! 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
$!
$! In case of problems with the install you might contact me at
$! zinser@decus.decus.de (preferred) or martin_zinser@exchange.de

$! Look for the compiler used
