Interesting.  Do you have pexports.exe or some other tool that can
display the exports of a DLL?  (Not sure pexports supports 64-bit
DLLs, though.)  If so, can you look in your gdi32.dll and see whether
it really exports this function?  If it doesn't, then this looks like
a problem with the import libraries, although I see no problem in
changing the order of the link command line to fix it.
