40 Wrapper for compilers which do not understand `-c -o'.
41 Remove `-o dest.o' from ARGS, run PROGRAM with the remaining
42 arguments, and rename the output as expected.
44 If you are trying to build a whole package this is not the
45 right script to run: please start by reading the file `INSTALL'.
47 Report bugs to <bug-automake@gnu.org>.
