-mmacos-version-min= is the current Apple option.  However, the gfortran 
build recommended in the manual is quite old and this has apparently 
differed by GCC version (and is not documented in the 'man gfortran' I 
have).

I'll change the manual to mention both forms, and that it is only 
sometimes needed (not on my current setup).
