as I elaborated, if you choose to implement GNU extensions you can
write it in such a way that the program prints a warning that such GNU
extensions are used. This way it is possible to notice derivations from
the standard, as all available tools currently "silently" support
non-portable extensions.

There are tools already to detect "bashisms" in shell-scripts, so maybe
another interesting approach would be to write a tool that detects
gmakeisms in Makefiles. However, given this would probably involve
parsing such files anyway, you could directly go ahead and implement a
sane make.

With best regards
