Subject: Interfacing Gnat to Fortran Complex*16

Has anyone tried and succeeded in interfacing Ada code compiled with
Gnat (gcc 3.4.2 version) to Fortran code, passing double precision
complex arrays to the Fortran code (Complex*16)?
Background: the LRM Annex B specifies only single precision complex
in Interfaces.Fortran, and I have code for which this works (I am
interfacing to the LAPACK numerical library). LAPACK contains a
double precision version of the routine I am using and I would like
to interface to it.
Problem: although the single precision routine works fine, the double
precision code goes into an apparently infinite loop.
