swig/Source/Swig/swig.h
Dave Beazley 8a7d0af5ad Changed the handling of types in parameter lists and removed the %val 
and %out directives.    This result of this change is that SWIG does
a lot less manipulation of types before they are given to language
modules.  It also means that a lot of stuff is going to be broken
for a short period of time.   I am working on cleaning all of this up
so give me a few days to sort it out.
