This should be faster, smaller and easier * to use. * * This is the first check-in of his code before I start futzing with it! * * Revision 1.5 2002/01/30 07:54:53 damo * Fixed up the libtool versioning stuff (finally) * Fixed bug 500600 (not detecting a NULL return from malloc) * Fixed bug 509485 (no longer needs search.h) * Cleaned up debugging section * Allow multiple inclusions of redblack.h * Thanks to Matthias Andree for reporting (and fixing) these * * Revision 1.4 2000/06/06 14:43:43 damo * Added all the rbwalk & rbopenlist stuff. Fixed up malloc instead of sbrk. * Added two new examples * * Revision 1.3 2000/05/24 06:45:27 damo * Converted everything over to using const * Added a new example1.c file to demonstrate the worst case scenario * Minor fixups of the spec file * * Revision 1.2 2000/05/24 06:17:
