Re: [Fortran,patch] PR 39178 - inline main()

Seems to be reasonable. I then would suggest to deprecate it
with such a warning in 4.5 and remove it in 4.5.

The question is whether one wants to still keep the
rest of libgfortran/fmain.c (to allow older programs to link,
where the main program has not been compiled with gfortran 4.5)
or whether one removes it completely.

How about creating a proper patch?

None in this case. The Fortran main program is in the
function "MAIN__" due to historic reasons (this is the
case in several Fortran compilers).

However, libgfortranbegin contains the normal "main()" as
known from C, which does some initializations and then
calls MAIN__. See libgfortran/fmain.c for how little is
done in libgfortranbegin.a.
