I don't think you should be exporting your DLL entry point, but that
shouldn't matter in this case I don't think.

Could you try out dllhelpers-0.2.4 and see if that helps? It provides
a portable DLL init function (incorporated in upcoming b20) which 
takes care of attaching to the DLL correctly.

If you've marked your exports in the code,
  
  $ dllwrap --add-stdcall-alias -o foo.1.dll [objs ...] [libs ...]

or, if you already have DEF file,

  $ dllwrap --def foo.1.def -o foo.1.dll [objs ...] [libs ...]

--add-stdcall-alias adds the aliases for @ symbols:
  
  EXPORTS
    foo AT 0 @ 1;
    foo = foo AT 0 @ 2;

Use the default entry point and DLL main instead of supplying your
own. See the examples. 

http://www.xraylith.wisc.edu/~khan/software/gnu-win32/ for download
info. The ftp site also has some examples of LoadLibrary -- see 
the loadlib-example*.tar.gz files.
