The test below shows that GetStaticFieldID cannot access "itrf_fld" field
of the class gsfi00101 which is inherited from the interface "Interf".

To run the test, set environment variables JH (Java home) and CC (C compiler)
and run "jnirun" script.

./jnirun
GetStaticFieldID: cannot get interface field
Exception caught: java.lang.NoSuchFieldError: itrf_fld
