| 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. |
