<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.
</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:

<p>
<i>
   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.</i>

</P>
