Changes between 1.4a3 and 1.4a4 (29-Jul-2000 to 24-Mar-2001)
+ *) Implemented the pthread_{set,get}concurrency() API parts of
+ POSIX/SUSv2, although internally we are (allowed to be) free to not
+ do anything based on the requested level.
+ [Ralf S. Engelschall, Bill Apt <babt@us.ibm.com>]
+
*) Adjusted all pthread_attr_getXXXX() functions to use a "const
pthread_attr_t *" as the first argument instead of "pthread_attr_t
*" to fully-conform to POSIX/SUSv2.
