+       * Added silc_stack_[set|get]_global to set/get global per-thread
+         SilcStack.  Affected files are lib/silcutil/silcstack.[ch].
+
+       * Imported new improved free regex implementation.  Added (again)
+         support for SILC_REGEX_NOTBOL and SILC_REGEX_NOTEOLF flags.
+         Added also support for POSIX bounded repeat expression (a{n,m}) 
+         to make it more POSIX compliant.  Added SilcStack support to
+         the regex too.  Affected files are lib/silcutil/silcregex.[ch].
+
+       * Added silc_buffer_printf to lib/silcutil/silcbuffer.h.
+
+       * Changed silc_srealloc to allocate new memory block if reallocation
+         from stack fails, and to copy the old data to the new one.
+         Affected files are lib/silcutil/silcmemory.[ch].

+ * DESCRIPTION
+ *
+ *    Sets global SilcStack `stack' that can be retrieved at any time
+ *    by using silc_stack_get_global.  The global stack is global only
+ *    to the current thread.  Each thread can have their own global stack.
+ *    If each thread must have own stack this must be called in each
+ *    thread.  If the global stack has been set already, new call will
+ *    replace the old one.
+ *
+ *    This routine is provided only as a convenience function to store
+ *    program's or thread's stack in one global place.  It is not mandatory
+ *    to call this function in order to use SilcStack.
