Error: PUBLIC function 'f1' at (1) cannot be of PRIVATE type 't1'

gfortran has two bugs:
a) F1 is an internal function and thus PUBLIC/PRIVATE does not apply
b) If one makes F1 a (PUBLIC) *module* function, the program still would be a
valid Fortran 2003 program (and an invalid Fortran 95 program).

I still need to test whether the original program is fixed or not; there are
quite a lot files ...
