Ah, great, thank you.

I suggested it before, maybe we could use '$(CC) -dumpversion' in an
environment variable, say GNUSTEP_COMPILER_VERSION, to be able to write
more flexible makefiles with respect to compiler options, eg.

  #
  # common flags
  #
  ADDITIONAL_OBJCFLAGS += [...]

  #
  # specific compiler flags
  #
  if eq($(GNUSTEP_COMPILER_VERSION, 33)

  ADDITIONAL_OBJCFLAGS += -fno-strict-aliasing -Wundeclared-selector

  endif
