Subject: libtool Doesn't Export C++ Methods on AIX

I'm trying to use libtool with C++ programs, and found that libtool
wouldn't put any C++ methods into the shared library. When I looked
into it, I found that the nm command used to create the export list
doesn't pass a -C flag. On AIX, the -C flag says to leave C++ names
mangled. Since the function names weren't mangled, the sed line
didn't recognize them as functions, so they weren't put into the .exp
file. I found that I could fix the problem by adding a -C flag to
ac_cv_path_NM in config.guess. I suppose the configure script should
check for that and do it automatically.
I'm running libtool version 1.2 on an AIX 4.2 box
(powerpc-ibm-aix4.2.1.0).
I have some test files that I can give to anyone who wants to test
this. And I can test potential fixes on my machine.
Thank you,

libtool messes up on AIX when using GNU ld. It doesn't set
archive_cmds to anything useful.
Here is a hack patch. This should be fixed in a better way. For one
thing, GNU ld supports the -unix option to export all symbols, so the
stuff using nm is probably not necessary.
