           Summary: gfortran invoking cc1 on AIX
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran

cc1: error: unrecognized command line option '-fdump-fortran-original'
collect2: fatal error: gcc returned 1 exit status
compilation terminated.
compiler exited with status 1

On AIX collect2-ld is a wrapper around the linker.  It finds static
initializers and finalizers, writes them to a file, and compiles them with gcc.
 It passes the command line arguments to gcc.

Compiling and linking a GNU Fortran program with a single command line causes
Fortran options to be passed to cc1 through collect2, causing cc1 to report a
fatal error of an unrecognized command line option.
