[Patch, Fortran] PR 42353: [OOP] Bogus Error: Name 'vtype$...' at (1) is an ambiguous reference ...

[Janus Weil]

Hi all,

the attached patch fixes a small OOP problem, where under certain
circumstances one would get 'ambiguous reference' errors for the
vtypes. The easiest thing I could think of to fix this is to make the
vtypes private, which means that each module which uses a vtype will
have its own private copy (which in principle should not be a problem,
should it?).

The patch was successfully regtested on x86_64-unknown-linux-gnu. Ok for trunk?

Cheers,
Janus
