<H3>Status</H3>
<P>Compiling this library requires a recent version of gcc.  (For instance,
   gcc 2-95 works well.)  In addition, <A HREF="/autoconf/">autoconf</A>
   versions 2.13 and above and <A HREF="/automake/">automake</A> versions
   1.3b and above are required and essential ingredients for those mucking
   about in the Makefiles and trying to configure on new targets.  Other
   tools and complete installation instructions can be found in
   <A HREF="install.html">the installation page</A>.
</P>

<P>New things that work are in the latest
   <A HREF="17_intro/RELEASE-NOTES">release notes</A>.
</P>

<P>Known problems and bugs, which will force us to actually keep this
   file up-to-date, can be found in <A HREF="17_intro/BUGS">bugs</A>.
</P>

<P>Things that need to be done and are looking for volunteers can be found
   in: <A HREF="17_intro/TODO">pick me</A>.
</P>

<P>This release has been tested with gcc 2.95 on the following
   platforms.  The configuration of --disable-namespaces
   --disable-libgcc-rebuild was tested. Results for the
   --enable-namespaces builds should be comparable.  Here are the
   results for snapshots 2.90.N:

<P>Note 1: A newer compiler than gcc-2.95.2 is required. 
</P>

<P>Note 2: All solaris toolchains were configured with --with-gnu-ld
--with-gnu-as --with-gnu-binutils --with-gcc. (That's a lot of --with's...)
</P>

<P>Note 3: Configuration and initial support for AIX has been
   completed. However, problems with the compiler/linker have
   prevented testing. For instance, mknumeric_limits will fail unless
   weak linking is possible, which doesn't seem possible on
   AIX. The initial bug report is 
   <a href="http://gcc.gnu.org/ml/gcc-bugs/2000-03/msg00574.html"> here </a>

<P>And the response from one of the powerpc port maintainers:
   <BLOCKQUOTE><EM>
   I opposed the original solution (involving weak symbols) on ELF, as
   it seemed to be the wrong idea.  I'm not sure what the right fix is,
   and don't think I have time to work on it right now.
   </EM></BLOCKQUOTE>
