- $! If you are using a version of GCC that supports global constants

- $! 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.
