| $! 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. |
