[Bug fortran/17091] New: gfortran MAIN__ symbol not marked TREE_PUBLIC

["dje at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

When gfortran synthesizes the MAIN__ symbol, the decl is not receiving the
attribute TREE_PUBLIC, which is causing problems on AIX because the symbol is
not being globalized.

(gdb) break assemble_start_function
Breakpoint 5 at 0x10103808: file /farm/dje/src/src/gcc/varasm.c, line 1184.
(gdb) run foo.f90

    fnname=0x200c4855 "MAIN__") at /farm/dje/src/src/gcc/varasm.c:1184
(gdb) print decl->common.public_flag
