+    <li> <b>26 November 2001, powerpc shared libraries fully working</b>
+    <br>
+    Dave Schleef finished off the the work needed for shared library support on
+    powerpc.  There had been a few problems remaining, and those are now squashed.
+    So shared libs on powerpc should be working fully now.
+
+    <p>
+    <li> <b>14 November 2001, m68 compiles again, Large file support working</b>
+    <br>
+	About a month ago I synced the header files with glibc 2.2.4 for better
+	C++ support and better standards compliance.  I forgot to sync up m68k,
+	sparc, powerpc, and mipsel.  Dave Schleef fixed powerpc while he was fixing
+	up the shared lib loader.  I just fixed up m68k, sparc, and mipsel so they
+	should all compile again.
+	<p>
+	I also finished up fixing large file support (just enable DOLFS in your
+	Config file to enable it) and it is working just great, and greatly increases
+	the number of glibc applications that will work "out-of-the-tarball" without
+	needing any changes.
+
+
+    <li> <b>12 November 2001, powerpc shared lib support</b>
+    <br>
+	Thanks to David Schleef, uClibc now has full shared library support 
+	on powerpc.  This brings full shared library support to x86, ARM, and 
+	now powerpc.  Thanks Dave!
+
+
+    <p>
+    <li> <b>7 November 2001, uClibc application list</b>
+    <br>
+	uClibc now has a <a href="http://uclibc.org/uClibc-apps.html">list of applications</a> 
+	that are known to work.  If you have any applications to add to the
+	list, submissions are welcome!
+
+
+    <p>
+    <li> <b>18 October 2001, buildroot uClibc example system</b>
+    <br>
+
+	Those wanting an easy way to test out uClibc and give it
+	a test drive can download and compile 
+	<a href="ftp://uclibc.org/buildroot.tar.gz">buildroot.tar.gz</a>.   This
+	is a nifty buildsystem that will automagically download and build
+	a <a href="http://user-mode-linux.sourceforge.net/">User-Mode Linux</a>
+	kernel, and will then download source for and compile up a fully
+	working uClibc based root filesystem.  This should make it easy for
+	people to create their own projects.  I hope that this build system
+	will allow people to more easily use and build uClibc based systems.
+	As an example of how nicely this works, the 
+	<a href="http://tuxscreen.net/">Tuxscreen Project</a> is using a
+	<a href="http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/tuxscreen/buildroot-tux/">slightly adjusted variant of the buildroot system</a> to cross 
+	compile the blob bootloader, linux kernel, and a uClibc based jffs2
+	root filesystem (busybox, tinylogin, udhcp, lrzsz, pcmcia-cs and 
+	microwindows) for ARM.  Pretty cool.
+
+
+
+    <p>
+    <li> <b>11 October 2001, v850 architecture support</b>
+    <br>
+
+	Miles Bader has contributed support for the v850 architecture.
+
+
+    <p>
+    <li> <b>25 Spetember 2001, header files updated</b>
+    <br>
+
+	uClibc's header files are now in sync with glibc 2.2.4,
+    allowing better standards compliance, better portibility, and 
+    better C++ support.
+    
+    <p>
+    <li> <b>4 July 2001, ARM shared library support</b>
+    <br>
+
+	uClibc now has full shared library support on ARM.
+
+
+    <p>
+    <li> <b>9 May 2001, libm added</b>
+    <br>
+
+	uClibc now has a very complete math library.
+
+
+    <p>
+    <p> <li> <b>9 May 2001, ld.so added</b>
+    <br>
+
+	uClibc now has a native ld.so.  It currently is only ported to work on x86,
+	but porting to other architectures should not be too difficult.
+
+
+    <p> <li> <b>15 March 2001, powerpc port added</b>
+    <br>
+
+	David Schleef contributed a powerpc port, which is now in CVS.
+
+    <p> <li> <b>19 February 2001, SH port added</b>
+    <br>
+
+	Jean-Yves Avenard contributed an SH port.  See his email 
+	with the initial patch <a href="http://uclibc.org/lists/uclibc/2001-February/000409.html">here</a>.
+
+    <p> <li> <b>16 January 2001, uClibc as a shared library</b>
+    <br>
+
+	 As if January 16, uClibc can now be used (at least on x86) as a shared
+	library.  See the <a href="http://uclibc.org/lists/uclibc/2001-January/000126.html">email</a>
+	announcing this achievement.
+
+    <p> <li> <b>11 January 2001, gcc wrapper added</b>
+    <br>
+
+	Manuel Novoa III has created a wrapper for gcc that makes compiling apps vs uClibc
+	as simple as just setting "CC" to gcc-uClibc-&lt arch&gt.  This even works when cross
+	compiling!  Very cool.
+
+    <p> <li> <b>3 January 2001, uClibc now has a web page</b>
+    <br>
+
+	 A lot of work has been going on under the hood with uClibc,
+	 so I decided to put together this webpage to let the world know
+	 that it exists and is getting to be very usable.

+Here are a few things on the TODO list:

+    <li> Shared library support for all supported architectures.

+    <li> Shared library support for mmu-less systems.  This is
+	very doable (think of C++ vtables for example), but will

+
+This history and origin of uClibc is long and twisty.
+In the beginning, there was <a
+href="http://www.gnu.org/software/libc/libc.html">GNU libc</a>.  Then, libc4
+(which later became linux libc 5) forked from GNU libc version 1.07.4, with
+additions from 4.4BSD, in order to support Linux.  Later, the <a
+href="http://www.cix.co.uk/~mayday/">Linux-8086 C library</a>, which is part of
+the <a href="http://www.elks.ecs.soton.ac.uk/">elks project</a>, was created,
+which was, apparently, largely written from scratch but also borrowed code from
+libc4, glibc, some Atari library code, with bits and pieces from about 20 other
+places.  Then uClibc forked off from the Linux-8086 C library in order to run
+on <a href="http://www.uclinux.org">ľClinux</a>.  
+<p>
+
+I had for some time been despairing over the state of C libraries in Linux.
+GNU libc, the standard, is very poorly suited to embedded systems (and it just
+gets bigger with every release).  I spent quite a bit of time looking over the
+other Open Source C libraries that I knew of (listed below), and none of them really
+impressed me.  I felt there was a real vacancy in the embedded Linux ecology.
+The closest library to what I imagined an embedded C library should be was
+uClibc.  But that had a lot of problems too -- not the least of which was that,
+traditionally, uClibc had a complete source tree fork in order to support each
+and every new platform, resulting in a big mess of twisty versions, all
+different.  I decided to fix it and the result is what you see here.
+My source tree has now become the official uClibc source tree and it now lives 
+on cvs.uclinux.org.  
+
+<p>
+
+To start with, (with some initial help from <a
+href="http://www.uclinux.org/developers/index.html">D. Jeff Dionne</a>), I
+ported it to run on x86.  I then grafted in the header files from glibc 2.1.3
+and cleaned up the resulting breakage.  This (plus some additional work) has
+made it almost completely independant of kernel headers, a large departure from
+its traditional tightly-coupled-to-the-kernel origins.  I have written and/or
+rewritten a number of things that were missing or broken, and sometimes grafted
+in bits of code from the current glibc and libc5.  I have also built a proper
+platform abstraction layer, so now you can simply edit the file "Config" and
+use that to decide which architecture you will be compiling for, and whether or
+not your target has an MMU, and FPU, etc.  I have also added a test suite,
+which, though incomplete, is a good start.  Several people have helped by 
+contributing ports to new architectures, and a lot of work has been done on
+adding support for missing features.
