and development branches, including but
not limited to:
- 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.

cast until after the double in question has been determined to be
finite, not NaN, etc. This may make the code a little more XP for
platforms like BSD and Alpha Linux that don't like casting strange
values to int. Thanks go to Uncle George <gatgul@voicenet.com> and

+ Changed the way JS wrapper functions for Java instance methods are constructed.
Previously, these were computed the first time that an instance method was
accessed for a particular JavaObject and cached in the native, private portion
of that JavaObject. However, the required call to JS_AddRoot() causes an root
to appear as a link in a cyclical graph, leading to uncollectible objects, i.e.
the JavaObject has a root pointer to the function object and the function has
a parent that points back to the JavaObject. Now, we compute the functions
at the time a class is reflected and use JS_CloneFunctionObject() each time
a JS wrapper function is needed, which is slower, but avoids this GC problem.
