| Wrapper for compilers which do not understand `-c -o'. |
| Remove `-o dest.o' from ARGS, run PROGRAM with the remaining |
| arguments, and rename the output as expected. |
| |
| If you are trying to build a whole package this is not the |
| right script to run: please start by reading the file `INSTALL'. |
