[f2py] callback parsing bug

[Curtis Jensen]

Pearu,
I've run into a parsing problem with the callback functions.  With the
attached Fortran file, I get the following errors when using f2py (ver
2.315)

f2py mycb.f -m mycb
Reading fortran codes...
        Reading file 'mycb.f'
Post-processing...
        Block: mycb
                        Block: mycb

    def isstring(var): return var['typespec']=='character' and (not
isexternal(var))
KeyError: typespec


However, if I comment out the "implicit none" line, then everything
works fine.  I only have trouble with the "implicit none" line when
using external functions.  I would like to keep the "implicit none"
capability.  Unfortunatly, I don't know the f2py code well enough to
find the bug for you.  
Thanks.
