Having just looked at the list of complex library functions, which is  
going to be easier (or a more efficient use of time):  writing them in  
Modula-2 (or perhaps C with an appropriate wrapper) or using the  
Fortran intrinsics (again with a wrapper which is probably less  
transparent than the C wrapper because of call-by-reference versus  
call-by-value)?  The latter would undoubtedly require adding gfortran  
to the list of required languages for the gm2 build (just to get the  
libraries).
