Version 1.3.32 (in progress)
============================
09/05/2007: wuzzeb (John Lenz)
- Change r_ltype in typesys.c to store a hashtable instead of a single value.
several very subtle bugs were being caused by multiple ltypes being mapped
to a single mangled type, mostly when using typedefed template parameters.
Now, r_ltype stores a hashtable of possible ltypes, and when generating the
type table, all the ltypes are added into the swig_type_info structure.
