             Bug #: 57048
           Summary: [4.9 Regression] Handling of C_PTR and C_FUNPTR leads
                    to reject valid
    Classification: Unclassified
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Keywords: rejects-valid
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: burnus@gcc.gnu.org


Reported by Angelo Graziosi at
http://gcc.gnu.org/ml/fortran/2013-04/msg00210.html

Using in file1:
  module m
  ...
    type t
      type(c_funptr) :: funptr
    end type

and in file2:
   use iso_c_binding, ONLY: c_funloc
   use m
   type(t) :: x
   ...
   x%funptr = c_funloc(proc)

fails with:
  Error: Can't convert TYPE(c_funptr) to INTEGER(4) at (1)


The problem is that the .mod file only contains:
  win32_types.mod:5 'C_funptr' '__iso_c_binding' '' 1 ((DERIVED UNKNOWN-INTENT
while the symtree is searched for "c_funptr".

Workaround: Editing the .mod file and changing C_funptr to c_funptr.

On x86_64-apple-darwin13, I get with gfortran 4.8.2

What is setting the capital C and why?

This fixes this case;
However, it is not free of regressions.

Created attachment 31956

Bigger patch (doesn't work better :-/ )

And this is how far I got before giving up.
