451 - Accomodate finalization requests for static objects.
452 (Will be required by hash synchronization. May be needed
453 in some configurations now.)
456 - Define MIN_WORDS. All allocation requests are rounded
457 up to at least this size. Removes a subtle assumption that
458 Java objects have a 2 word header.
461 - Adjust Linux/IA64 configuration for non-ancient kernels.
462 (Necessary fix for IA64.)
465 - Fix syntax error in currently unused code. Will be needed
473 - Change stack cleaning code to typically clear about one tenth
474 the memory it used to in the threads configuration. Occasionally
475 still clear more. (This is really a fix for a long-standing
476 and fairly significant performance bug with threads.)
479 - Fix the code for finding the beginning of the data segment under
480 Linux. I believe this is necessary for some IA64 Linux
481 distributions. It will also helo other platforms, though those
482 may additionally require a gcconfig.h adjustment. (This basically
483 works around the absence of a data_start or __data_start
484 definition in glibc.)
487 - Handle rounding due to MIN_WORDS.
