$! Command file to build a GNU assembler on VMS

$! If you are using a version of GCC that supports global constants
$! you should remove the define="const=" from the gcc lines.
$!
$! Caution: Versions 1.38.1 and earlier had a bug in the handling of
$! some static constants. If you are using such a version of the
$! assembler, and you wish to compile without the "const=" hack,
$! you should first build this version *with* the "const="
$! definition, and then use that assembler to rebuild it without the
$! "const=" definition. Failure to do this will result in an assembler
$! that will mung floating point constants.
$!
$! Note: The version of gas shipped on the GCC VMS tapes has been patched
$! to fix the above mentioned bug.
