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'.
