[RFC]: Patch to support Fortran derived type - testcase

[Wu Zhou <woodzltc at cn dot ibm dot com>]

Hi,

This is the testcase for the patch. To run this, we need to set 
F77_FOR_TARGET=gfortran.  Maybe we need dejagnu to support gfortran 
itself.

I had tested it on FC4 with gfortran being 4.0.1. No failure is detected. 
All 11 tests passed.
