  11 $!      If you are using a version of GCC that supports global constants
  12 $!      you should remove the define="const=" from the gcc lines.
  13 $!
  14 $!      Caution:  Versions 1.38.1 and earlier had a bug in the handling of
  15 $!      some static constants. If you are using such a version of the
  16 $!      assembler, and you wish to compile without the "const=" hack,
  17 $!      you should first build this version *with* the "const="
  18 $!      definition, and then use that assembler to rebuild it without the
  19 $!      "const=" definition.  Failure to do this will result in an assembler
  20 $!      that will mung floating point constants.

  23 $!      to fix the above mentioned bug.
