+	version of glibc installed.  What's wrong?
+
+{ZW} Glibc on one of these systems was compiled with gcc 2.7 or 2.8, the
+other with egcs (any version).  Egcs has functions in its internal
+`libgcc.a' to support exception handling with C++.  They are linked into
+any program or dynamic library compiled with egcs, whether it needs them or
+not.  Dynamic libraries then turn around and export those functions again
+unless special steps are taken to prevent them.
+
+When you link your program, it resolves its references to the exception
+functions to the ones exported accidentally by libc.so.  That works fine as
+long as libc has those functions.  On the other system, libc doesn't have
+those functions because it was compiled by gcc 2.8, and you get undefined
+symbol errors.  The symbols in question are named things like
+`__register_frame_info'.
+
+For glibc 2.0, the workaround is to not compile libc with egcs.  We've also
+incorporated a patch which should prevent the EH functions sneaking into
+libc.  It doesn't matter what compiler you use to compile your program.
+
+For glibc 2.1, we've chosen to do it the other way around: libc.so
+explicitly provides the EH functions.  This is to prevent other shared
+libraries from doing it.  You must therefore compile glibc 2.1 with EGCS
+unless you don't care about ever importing binaries from other systems.
+Again, it doesn't matter what compiler you use for your programs.
