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