>Description:
	

If you are using a compiler, like gcc45, in a port, then libtool doesn't always work properly.
>How-To-Repeat:
Try to build the vis5d+ port.

You will get an error like this

multiple definition of `__i686.get_pc_thunk.bx
	
>Fix:

	

Here is one suggestion.  It causes libtool to respect $CC and $CXX.  But you would have to do this for the other tools used for linking.

This will add a new file called patch-configure.
