I don't know what AVR is; is it some kind of Windows-based thing?

GNU make invokes the subprocess you specify, then tries to determine if
it worked or not.  It does this based solely on the exit code of the
subprocess: if it exits with zero (which is EXIT_SUCCESS), then the program
succeeded.  If it exits with any other value, that means to make that
the program failed.

This message ("*** make.exe: [kw.o] Error 11") means that the subprocess
make invoked (avr-gcc) exited with a non-zero value (11, in this case).

Thus make believes the subprocess failed.

The right answer here is to find out why avr-gcc is exiting with a
failure exit code if it really succeeded.

Another possibility is to modify the GNU make code so that it treats
exit codes other than zero as success as well; perhaps that's what they
did for the AVR port.  But, that's a broken, hack solution.  IMHO :).

If you issue the gcc command manually, then check its exit code, you'll
find it exited with an exit code of 11 rather than the correct 0.
