| 5 | # In order to use this stub, the following makefile variables must be defined. |

| 20 | # This is a horrible hack to try to find libgcc.a --- the DLL documentation |
| 21 | # states that you should just be able to do -lgcc, but modern gcc |
| 22 | # installation packages don't install /usr/lib/libgcc.a --- as well they |
| 23 | # shouldn't since libgcc.a can be gcc version dependent. |
| 24 | # If this hack doesn't work, try replacing it with a hardcoded path to |
| 25 | # libgcc.a, or -lgcc. |
