Never mind my previous message. I forgot the provided init.el file,
which makes all the difference.

Confirmed.

By default, ob-fortran (and at least ob-C) wrap the src block body to
become a standalone function unless you put :main no header argument.

The default behaviour is mostly useful during execution, but not when
tangling.

I will need to think about the best way to approach this. A tentative
fix would be handling :main header argument only during block evaluation.

Meanwhile, you can set :main no as default header argument for fortran.
