+Some users reported (rare) linkage errors with gcc-2.95.2, which where
+replaced by other errors in recent snapshots.
+The latest release of binutils had bugs in the handling of weak symbols

+Quintessence: gcc-users under hpux-10 should use gcc-2.95.2 until they really
+have problems with it. Precompiled packages of gnu software may be found at <a
+href="http://hpux.cs.utah.edu/">the Software Porting And Archive Centre for
+HP-UX</a>.  Everybody is welcome to test newer snapshots and report errors
+to the appropriate mailing lists, but should be aware of the fact that there
+might still be things yet to be fixed.

+<h3><a name="hppa*-hp-hpux11">hppa*-hp-hpux11</a></h3> <p>Regarding hpux-11,
+support for it is new in binutils and gcc.  There is no official release of gcc
+that supports it. If You wish to experiment with a recent snapshot of gcc, the
+use of a recent snapshot of binutils is obligatory. The latest release of
+binutils had bugs in the handling of weak sysmbols under hpux.  See the <a
+href="http://sources.redhat.com/binutils/">binutils home page</a> for more
+information.
+</p>
+<p>
+It is recommended to install <code>bison</code>, <code>gmake</code> and to use
+<code>cvs</code> as described at <a
+href="http://gcc.gnu.org/cvs.html">http://gcc.gnu.org/cvs.html/</a>, in order to
+obtain the most recent versions of gcc/binutils.<br> Precompiled packages of gnu
+software may be found at <a href="http://hpux.cs.utah.edu/">the Software Porting
+And Archive Centre for HP-UX</a>.
+
+If You encounter problems in building binutils due to missing 
+symbol <code>alloca(code)</code> a possible workaround is to 
+set environment variables <code>ac_cv_header_alloca_h</code> and 
+<code>ac_cv_func_alloca_works</code> to <code>no</code> 
+and retry with <code>make distclean; ./configure ; make</code>
+</p>
+<p>
+When configuring gcc we encourage the explicit specification of the
+gnu-assembler and its absolute path. Example:<br>
+<code>[build-dir] # ../gcc/configure --prefix=/opt/gcc-today \<br> 
+--with-gnu-as \<br> --without-gnu-ld \<br> --with-as=/opt/binutils-today/bin/as</code>
+</p>
+<p>
+Like on hpux-10, the HP assembler inserts timestamps
+into each object file it creates, causing the 3-stage comparison test to fail
+during a `<code>gmake bootstrap</code>'.  You should be able to continue by 
+saying `<code>gmake all</code>' after getting the failure 
+from `<code>gmake bootstrap</code>'.
+</p>
+<p>
+Situation for gcc on hpux-11 changes daily at the moment, so most of the
+problems may resolve in near future. Nonetheless every helpful 
+contribution like patches or explanations for build or runtime failures
+is always welcome.
