+The base NPTL code for uClibc is from the glibc project located at
+<http://sourceware.org/glibc/>. The starting version was the HEAD of
+the glibc CVS repository dated 2005-05-06. Important changes from
+glibc will continue to be brought in as necessary until the version
+for uClibc is standing on its own. All of the files were originally
+brought over verbatim with no modifications. Obviously, these will
+undergo any necessary changes needed for integration into uClibc.
+Additionally (or subtractingly), the files and directories below
+were removed and not imported.

+Now that the Linux kernel is once again able to run all the tests we
+have and since glibc 2.3 was released it was time for a new code drop.
+I've uploaded the second code drop for the Native POSIX Thread
+Library:
+
+  ftp://people.redhat.com/drepper/nptl/nptl-0.2.tar.bz2
+
+You need
+
+- the latest of Linus' kernel from BitKeeper (or 2.5.41 when it
+  is released);
+
+- glibc 2.3
+
+- the very latest in tools such as
+
+  + gcc either from the current development branch or the gcc 3.2
+    from Red Hat Linux 8;
+
+  + binutils preferrably from CVS, from H.J. Lu's latest release for
+    Linux, or from RHL 8.
+
+
+Compiling glibc should proceed smoothly.  But there are a number of
+tests which fail, mostly because some functionality is missing in
+glibc.  Ignore those errors.  It is only important that all tests in
+nptl/ are passing.  Run
+
+  make subdirs=nptl check
+
+to run all thread tests.
+
+
+This version features several improvements:
+
+- all APIs are now implemented;
+
+- fork handling has been improved; stacks in the child are freed;
+  atfork handlers are removed if they were registered from a module
+  which gets unloaded.
+
+- pthread_tryjoin_np and pthread_timedjoin_np are implemented
+
+- TSD handling corrected and optimized.
+
+- many more tests which also test the underlying kernel implementation.
+
+- the build infrastructure has been implemented so that the DSO and
+  archives are built in usable form and with correct named.
+
+- libthread_db has been implemented.  This is the library which is
+  needed by all program which need to get access to internals of
+  libpthread (mainly debuggers).
+
+- the CPU clock functions are implemented
+
+
+
+The white paper hasn't yet been updated.  It's still available at
+
+  http://people.redhat.com/drepper/nptl-design.pdf
+
+
+This release should be ready for some serious testing.  I know it is
+hard to compile which I why I'm looking into providing binary RPMs.
+They can be used on non-critical systems.  I'll only be able to
+provide binaries for RHL8 based systems, though, and the kernel still
+must be installed separately.
+
+
+The next steps will include:
+
+- write more tests and fix the bugs which are discovered this way
+
+- update the white paper
+
+- write and run more performance tests
+
+- port to IA-64
+
