     then you need to upgrade the version of the xforms library you have

-  o It is possible to compile lyx with Tru64 Unix cxx compiler
-    version 6.2, provided one uses
-	CXX='cxx -std strict_ansi'
-	CXXFLAGS='-ptr /tmp/lyx_cxx_repository -g'
-	CC=cc
-
-    Note that this will not work when compiling directly from the cvs
-    repository, due to the tricks used by automake for dependencies. Ask
-    Jean-Marc.Lasgouttes@inria.fr for a workaround.
-
-    Or rather, it may well work if you are using automake 1.5 and autoconf 2.5
-    or greater, but you'll have to patch automake's depcomp first. (Depcomp
-    is a little shell script to automagically work out file dependencies
-    and it's broken for automake 1.5 and Tru64 :-(). The patch is to be found
-    in config/depcomp.diff.
-    Angus 22 March, 2002.
-
-  o On Tru64 Unix, you may have to compile with
-    --with-included-string to work around a Tru64 linker limitation
-    (the STL string template creates names which may be too long). We
-    also had reports that it helps with gcc 2.95.2 on solaris 2.6.
-
-    Using Tru64 Unix 4.0e, the std::string is fine.
-    Angus 22 March, 2002.
-
-  o On Tru64 Unix with cxx, you may have a compilation error in
-    lyx_main.C if you have GNU gettext installed. This is due to a bug
-    in gettext. To solve this, you can either (1) configure with
-    --with-included-gettext or (2) add -D__STDC__ to cxx flags.
-
-  o On Tru64 Unix 4.0e, the STL library routine std::count is broken
-    (/usr/include/cxx/algorithm.cc, line 289 on my machine).
-    It calculates "n" but does not return it! The fix is to add "return n;" to
-    the end of the (4-line long) routine.
-    Angus 22 March, 2002.
-
-  o On Tru64 Unix 4.0e, compilation of support/lyxsum.C dies horribly. The
-    work-around is to use the old version, 1.18, of this routine. Ask
-    Angus Leeming <leeming@lyx.org> for details.
-    Angus 22 March, 2002.
-
-  o Some systems lack functions that LyX needs.  To fix this, configure
-    tries to link against the -liberty library, if it is available. 
-    If you experience problems with missing symbols at link time, you 
-    could try to install libiberty.a, which comes with several GNU 
-    packages (in particular libg++).  In any case, please report your 
-    problems to lyx-devel@lists.lyx.org.

-    The option --without-liberty disable the detection of -liberty.  It
-    is meant for debugging purpose only.

+    At the time of writing, cxx V6.5-026 is the latest cxx compiler. It is
+    /not/ recommended. Not only do the bugs in the system header files still
+    exist, but the compiler itself appears to be both buggy and extremely
+    bloated (trebles the size of the stripped LyX binary).
+
+    In order to compile LyX with the cxx compiler, you should run configure
+    with the following flags:
+	CXX='cxx -std strict_ansi'
+	CXXFLAGS='-nopure_cname -nocleanup -ptr /tmp/lyx_cxx_repository -O2'
+	CC='cc -std1'
+    The -nopure_cname flag is needed for compilers V6.3 and above because
+    LyX makes use of functions like popen, pclose that are defined in the
+    c version of <stdio.h> but are not formally part of any c/c++ standard.
+    They are not, therefore, included in the <cstdio> header file.
