[svn-r12362] Purpose:
Code checkpoint Description: Update fractal heap code to allow objects to be deleted Fix bugs in fractal heap object insertion Improve free space manager code to allow sections to be merged and shrink the container Another try at making the Windows compilers happy... Platforms tested: FreeBSD 4.11 (sleipnir) Mac OS X.4/PPC (amazon) Linux 2.4 (chicago & heping) Solaris 2.9 (shanti) AIX 5.? (copper) w/parallel
