MacOS X 10.5 and -export-symbols-regex

[Joe Orton]

We've had a report for Apache httpd that use of -export-symbols-regex is 
causing the produced DSO to be unusable with OS X 10.5.1.  This was with 
libtool 1.5.22:

http://issues.apache.org/bugzilla/show_bug.cgi?id=44384

I've CC'ed Giuliano, the reporter.  Can anybody help?  The module in 
question, mod_ssl, is linked using

   -module -avoid-version ... -export-symbols-regex ssl_module

(to avoid exporting anything other than the DSO entry point)

Regards,
