Hi, here's some more input for you:

As far as I know, this is a known issue with Apples currently shipping 
linker. I got the following response from an Apple employee:

Hopefully this will be solved in a future release of the tools.  Apple 
and the Darwin (Open source foundation of OSX) community
are working to get gcc 3.x  going.

The bug is filed as #2280846 at  http://www.opensource.apple.com/bugs/ , 
have a look.

OpenOffice (http://porting.openoffice.org/mac/) has the same issues and 
have some
info on how to work around it.

To get the latest info on these issues, try

Don't let this put you off, it may be easier than it sounds to get it to 
work...;-)
