development branch: - Preliminary exception handling per ECMA proposal; try, multiple catchblocks, and finally. Catchblocks are of the form catch (v) or catch(v:<guard>), where guard is an optional boolean expression that is evaluated to determine whether the exception is to be caught by that block. - ECMA-proposed 'in' operator; "'foo' in o" or "4 in o" asks if o has property foo or element 4. - Added a new set of defines in jsconfig.h for js 1.4 features-in-progress. (in, instanceof, exception handling.) Default build version is now 1.4. Fixed a few conditional features that had become broken. - Progress towards porting to FreeBSD and Alpha; casts of NaN and friends to int are a little more localized. Not there yet... - New config files to compile on more OSes; various fixes to improve portability.
