   3 # Currently depends on gcc, because:
   4 #  - the dependency tracking uses -MD in order to avoid needing an
   5 #    explicit `make depend' step
   6 #  - the definition of CFLAGS includes the gcc-specific flag
   7 #    `-Wall'
   8 #
   9 # Currently depends on GNU make, because:
  10 #  - the Makefile uses GNU ifdef / ifndef commands and GNU make `%'
  11 #    pattern rules
