I think I once tried to only do a
   gfc_new (gfc_symbol)
without creating a symtree; however, that was failing at other parts, 
which assume that every symbol has a symtree entry. I think when I tried 
it, it broke already for a single scoping unit - but I would assume that 
one also needs to heavily modify module.c. I am sure it will work, but I 
had the feeling that it will be more effort for little gain. The gain is 
that one avoids the capital letter trick and the difference between the 
symtree name and the symbol name. However, it creates a new imbalance: 
symbols which have a symtree vs. symtrees which have not.
