*
* Revisions :
* $Log: jcc.c,v $
+ * Revision 1.92.2.13 2003/11/27 19:20:27 oes
+ * Diagnostics: Now preserve the returncode of pthread_create
+ * in errno. Closes BR #775721. Thanks to Geoffrey Hausheer.
+ *
+ * Revision 1.92.2.12 2003/07/11 11:34:19 oes
+ * No longer ignore SIGCHLD. Fixes bug #769381
+ *
+ * Revision 1.92.2.11 2003/05/14 12:32:02 oes
+ * Close jarfile on graceful exit, remove stray line
+ *
+ * Revision 1.92.2.10 2003/05/08 15:13:46 oes
+ * Cosmetics: Killed a warning, a typo and an allocation left at exit
+ *
+ * Revision 1.92.2.9 2003/04/03 15:08:42 oes
+ * No longer rely on non-POSIX.1 extensions of getcwd().
+ * Fixes bug #711001
+ *
+ * Revision 1.92.2.8 2003/03/31 13:12:32 oes
+ * Replaced setenv() by posix-compliant putenv()
+ * Thanks to Neil McCalden (nmcc AT users.sf.net).
+ *
+ * Revision 1.92.2.7 2003/03/17 16:48:59 oes
+ * Added chroot ability, thanks to patch by Sviatoslav Sviridov
+ *
+ * Revision 1.92.2.6 2003/03/11 11:55:00 oes
+ * Clean-up and extension of improvements for forked mode:
+ * - Child's return code now consists of flags RC_FLAG_*
+ * - Reporting toggle to parent now properly #ifdef'ed
+ * - Children now report blocking to parent. This enables
+ * statistics in forked mode
+ *
+ * Revision 1.92.2.5 2003/03/10 23:45:32 oes
+ * Fixed bug #700381: Non-Threaded version now capable of being toggled.
+ * Children now report having been toggled through _exit(17), parents
+ * watch for that code and toggle themselves if found.
+ *
+ * Revision 1.92.2.4 2003/03/07 03:41:04 david__schmidt
+ * Wrapping all *_r functions (the non-_r versions of them) with mutex semaphores for OSX. Hopefully this will take care of all of those pesky crash reports.
+ *
+ * Revision 1.92.2.3 2003/02/28 12:53:06 oes
+ * Fixed two mostly harmless mem leaks
+ *
* Revision 1.92.2.2 2002/11/20 14:37:47 oes
* Fix: Head of global clients list now initialized to NULL
