+ * Win32 only: Enabling STRICT to fix a VC++ compile warning.
+ *
+ * Revision 1.88 2002/03/27 14:32:43 david__schmidt
+ * More compiler warning message maintenance
+ *
+ * Revision 1.87 2002/03/26 22:29:54 swa
+ * we have a new homepage!

+ * Revision 1.86 2002/03/25 17:04:55 david__schmidt

+ *
+ * Revision 1.85 2002/03/24 15:23:33 jongfoster
+ * Name changes
+ *
+ * Revision 1.84 2002/03/24 13:25:43 swa
+ * name change related issues
+ *
+ * Revision 1.83 2002/03/16 23:54:06 jongfoster
+ * Adding graceful termination feature, to help look for memory leaks.
+ * If you enable this (which, by design, has to be done by hand
+ * editing config.h) and then go to http://i.j.b/die, then the program
+ * will exit cleanly after the *next* request. It should free all the
+ * memory that was used.
+ *
+ * Revision 1.82 2002/03/13 00:27:05 jongfoster
+ * Killing warnings
+ *
+ * Revision 1.81 2002/03/12 01:42:50 oes
+ * Introduced modular filters
+ *
+ * Revision 1.80 2002/03/11 22:07:05 david__schmidt
+ * OS/2 port maintenance:
+ * - Fixed EMX build - it had decayed a little
+ * - Fixed inexplicable crash during FD_ZERO - must be due to a bad macro.
+ * substituted a memset for now.
+ *
+ * Revision 1.79 2002/03/09 20:03:52 jongfoster
+ * - Making various functions return int rather than size_t.
+ * (Undoing a recent change). Since size_t is unsigned on
+ * Windows, functions like read_socket that return -1 on
+ * error cannot return a size_t.
+ *
+ * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
+ * crashes, and also frequently caused JB to jump to 100%
+ * CPU and stay there. (Because it thought it had just
+ * read ((unsigned)-1) == 4Gb of data...)
+ *
+ * - The signature of write_socket has changed, it now simply
+ * returns success=0/failure=nonzero.
+ *
+ * - Trying to get rid of a few warnings --with-debug on
+ * Windows, I've introduced a new type "jb_socket". This is
+ * used for the socket file descriptors. On Windows, this
+ * is SOCKET (a typedef for unsigned). Everywhere else, it's
+ * an int. The error value can't be -1 any more, so it's
+ * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
+ * Windows it maps to the #define INVALID_SOCKET.)
+ *
+ * - The signature of bind_port has changed.
+ *
+ * Revision 1.78 2002/03/08 21:35:04 oes
+ * Added optional group supplement to --user option. Will now use default group of user if no group given
+ *
+ * Revision 1.77 2002/03/07 03:52:06 oes
+ * - Fixed compiler warnings etc
+ * - Improved handling of failed DNS lookups
+ *
+ * Revision 1.76 2002/03/06 22:54:35 jongfoster
+ * Automated function-comment nitpicking.
+ *
+ * Revision 1.75 2002/03/06 10:02:19 oes
+ * Fixed stupid bug when --user was not given
+ *
+ * Revision 1.74 2002/03/06 00:49:31 jongfoster
+ * Fixing warning on Windows
+ * Making #ifdefs that refer to the same variable consistently
+ * use #ifdef unix rather than mixing #ifdef unix & #ifndef OS2
+ *
+ * Revision 1.73 2002/03/05 23:57:30 hal9
+ * Stray character 's' on line 1618 was breaking build.
+ *
+ * Revision 1.72 2002/03/05 21:33:45 david__schmidt
+ * - Re-enable OS/2 building after new parms were added
+ * - Fix false out of memory report when resolving CGI templates when no IP
+ * address is available of failed attempt (a la no such domain)
+ *
* Revision 1.71 2002/03/05 18:13:56 oes
* Added --user option
