In case anyone is wondering, my libtool patch is at:
 http://www.daa.com.au/~james/files/libtool-1.4.2-expsym-linux.patch

This will patch the libtool.m4 file so that the resulting libtool script 
will handle -export-symbols-regex correctly on Linux.  I have another 
patch that should fix things on all ELF platforms using gnu ld, but I 
haven't tested it on any other systems.  It is available at:
 http://www.daa.com.au/~james/files/libtool-1.4.2-expsym.patch

I would appreciate reports of success or failure on other platforms with 
this patch.

James.
