Description of problem:

gfortran issues an error when compiling functions returning a char that have the RESULT keyword, as in:

function charfun6 (input) result(output) bind(c,name="charfun6")

whereas the following syntax, that means exactly the same:

function return_char(i) bind(C,name='return_char')

does compile correctly.

This bug was discoverd in the following thread in comp.lang.fortran:
http://groups.google.com/group/comp.lang.fortran/browse_thread/thread/037fa9f3c24ddfa6


Version-Release number of selected component (if applicable):

$ gfortran -v
Using built-in specs.
Target: x86_64-redhat-linux

Thread model: posix
gcc version 4.3.2 20081105 (Red Hat 4.3.2-7) (GCC)


How reproducible:

Compile the attached files charfun6.f90 and charfun7.f90, both are equivalent, so should work.

Steps to Reproduce:
1. $ gfortran -c charfun6.f90
2. $ gfortran -c charfun7.f90

  
Actual results:
gfortran issues the following warning:
$ gfortran -c charfun7.f90
charfun7.f90: In function ‘return_char’:
charfun7.f90:7: error: aggregate value used where an integer was expected


Expected results:
no error
