   1 ! Some basic testing that calls to the library still work correctly with
   2 ! -ff2c
   3 !
   4 ! Once the library has support for f2c calling conventions (i.e. passing
   5 ! a REAL(kind=4) or COMPLEX-valued intrinsic as procedure argument works), we
   6 ! can simply add -ff2c to the list of options to cycle through, and get
   7 ! complete coverage.  As of 2005-03-05 this doesn't work.
