  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'.
  
  Report bugs to <bug-automake@gnu.org>.
