Details:

This bug only manifests itself on a GNUstep MinGW windows installation.  I am
testing on a Windows 7 system, and I installed GNUstep MSYS System, GNUstep
Core, and GNUstep Devel from http://www.gnustep.org/experience/Windows.html.

Here's the problem:

NSClassFromString(@"RandomClass") returns nil if "RandomClass" resides in a
Dynamically Linked Library (DLL), AND "RandomClass" has not yet been used.  If
however I make a call like this:

Class foo = [RandomClass class];

right before I make my NSClassFromString(@"RandomClass") call then I no
longer notice the bug.  I have created a quick example code with a Makefile
that is attached, so just untar the code and try it out to verify this is not
working.
