41 | Wrapper for compilers which do not understand `-c -o'. |
42 | Remove `-o dest.o' from ARGS, run PROGRAM with the remaining |
43 | arguments, and rename the output as expected. |

45 | If you are trying to build a whole package this is not the |
46 | right script to run: please start by reading the file `INSTALL'. |
