! Verify that the Fortran runtime libraries are present in the linker
! invocation. These libraries are added on top of other standard runtime
! libraries that the Clang driver will include.

! NOTE: Clang's driver library, clangDriver, usually adds 'oldnames' on Windows,
!       but it is not needed when compiling Fortran code and they might bring in
!       additional dependencies. Make sure its not added.

!       executable and may find the GNU linker from MinGW or Cygwin.
