             Bug #: 51792
           Summary: [4.7 regression] fortran bootstrap failure: no
                    previous prototype for 'resolve_typebound_function'
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: mikpe@it.uu.se


Bootstrapping gcc-4.7-20120107 with fortran enabled and
--disable-build-poststage1-with-cxx fails with:

prototype for 'resolve_typebound_function' [-Werror=missing-prototypes]
cc1: all warnings being treated as errors

This is because r182754 (PR 46262 + 46328 + 51052 fix) deleted the 'static' for
resolve_typebound_function, even though nothing outside of resolve.c calls it,
and there is no previous prototype in scope.

Adding the 'static' back allows bootstrap to complete.

Yet another error missed due to the build-everything-with-c++-by-default
change.

Dear Mikael,

Thanks for that - the static was removed for one variant of the patches that
you cite so that the function could be called form interface.c. Indeed, as you
say, it did not throw up an error subsequently and so I missed it.

I am just about to commit on another PR, so I will fix this one at the same
time.

Confirmed.

Cheers

Paul
