Creating a makefile that fails with GNU Make

[Ed Avis]

I have a makefile written for Windows make programs such as
Microsoft's 'nmake' or 'dmake'.  These are fairly incompatible with
Unix make and GNU make, so this makefile will not work with GNU
make.  I would like to make this obvious.

Is there a way to give an error 'this makefile will not work with GNU
make' depending on (for example) the MAKE_VERSION variable?  This
should be without running any external commands except maybe echo,
since Windows won't have them.
