[CMake] F90 and legacy F77

[Arjen Markus]

Hello James,

I do not think this is going to work: object files created with g77
and gfortran are not compatible as far as I know.

What constructs are they? F90/95 has one or two deleted features
but most compilers will simply accept them, perhaps grudgingly.

Regards,

Arjen
