Thanks a lot Tom and Andrew for your reviews.

Please find the updated patch as an attachment. 
Now fortran specific runto_main is renamed as fortran_runto_main, which is inline with the other such procedures as go_runto_main etc.

OK, that's a valid point.

Maybe we should just make 'proc runto_main' smarter then?  Add some logic to pick a suitable name for the main function per-language?

Or maybe we should do 'proc fortran_runto_main' .... ?

I'd just like something that's more inline with the existing 'runto_main' in style I think..

Thanks,
Andrew
