  12 $!      If you are using a version of GCC that supports global constants
  13 $!      you should remove the define="const=" from the gcc lines.
  14 $!
  15 $!      Caution:  Versions 1.38.1 and earlier had a bug in the handling of
  16 $!      some static constants. If you are using such a version of the
  17 $!      assembler, and you wish to compile without the "const=" hack,
  18 $!      you should first build this version *with* the "const="
  19 $!      definition, and then use that assembler to rebuild it without the
  20 $!      "const=" definition.  Failure to do this will result in an assembler
  21 $!      that will mung floating point constants.
  22 $!
  23 $!      Note: The version of gas shipped on the GCC VMS tapes has been patched
  24 $!      to fix the above mentioned bug.
