I don't see how FFLAGS could be important here.  The ov-fcn-handle
file is written in C++ and I don't see that the tests in that file
depend in any way on parts of Octave that are written in Fortran.

The tests are simply bits of Octave code.  You can extract them
(omitting the %! comment marker, of course) and run them at the
command line.

To run Octave in the build directory, use the run-octave script.
