We use Version V171/VAX11:185 of the compiler.

If m2make is called in a directory without hidden sub-directories, 
it generates a makefile containing syntax erros. 
The subsequent make fails.

e.g.
   mkdir test
   cd test
   vi test.mod
   m2make test
   make  <- syntax error

Is is not always obvious, that you missed to give the m2hdir command.

But I agree, m2make is very powerful and straightforward, 
if you use one makefile per directory.
