Re: DLL replacement problem

Hi Nico,

It is worth noting that v2.15 of GNU ld (and the entire GNU Binutils 
package) has now been released.  It may not fix this particular problem 
but it would certainly be worth your while to upgrade to those sources.

This is almost certainly the case.  You should be able to create a DEF 
file to overcome this problem.  I would also suggest reading the linker 
manual's section on x86 specific options as some of these might be able 
to help you as well.
