Hi Ian,

Right.  It seems that two entries for the same symbol name are created 
in the hash table and I have yet to find out why.  ie an undefined entry 
for _f is created first and then a defined entry for _f is created 
afterwards.  What I have yet to discover is why the second entry does 
not just replace the first.  I think it must have something to do with 
the symbol being associated with a warning, but I have not yet found out 
exactly what is happening.

Cheers
   Nick
