 367         - Change stack cleaning code to typically clear about one tenth
 368           the memory it used to in the threads configuration.  Occasionally
 369           still clear more.  (This is really a fix for a long-standing
 370           and fairly significant performance bug with threads.)
 371
 372         * os_dep.c:
 373         - Fix the code for finding the beginning of the data segment under
 374           Linux.  I believe this is necessary for some IA64 Linux
 375           distributions.  It will also helo other platforms, though those
 376           may additionally require a gcconfig.h adjustment.  (This basically
 377           works around the absence of a data_start or __data_start
 378           definition in glibc.)
 379
 380         * test.c:
