Version 1.3.32 (in progress)
============================

New command line option -macroerrors. When supplied, this will force
the C scanner/parser to report proper location information for code contained
inside SWIG macros (defined with %define). By default, SWIG merely reports
errors on the line at which a macro is used. With this option, you
can expand the error back to its source---something which may simplify
debugging.

[Internals] Major overhaul of C/C++ scanning implementation. For quite
some time, SWIG contained two completely independent C/C++ tokenizers--
the legacy scanner in CParse/cscanner.c and a general purpose scanner
in Swig/scanner.c. SWIG still has two scanning modules, but the C parser
scanner (CParse/cscanner.c) now relies upon the general purpose
scanner found in Swig/scanner.c. As a result, it is much smaller and
less complicated. This change also makes it possible to maintain all
of the low-level C tokenizing in one central location instead of two
places as before.
***POTENTIAL FLAKINESS***
This change may cause problems with accurate line number reporting
as well as error reporting more generally. I have tried to resolve this
as much as possible, but there might be some corner cases.

[Lua] Added typemap throws for std::string*, typemap for SWIGTYPE DYNAMIC,
changed the existing throws typemap to throw a string instead of making a copy of
