How do I get Win32 to locate DLLs elsewhere (not really a Python thing)?

I don't remember the search order off the top of my head, but DLLs are
normally searched for in the following locations:

1. The directory where the loading .exe is.  For Python that can be
python.exe or pythonw.exe, but it also works if the DLL is where the .pyd
file is at if it is the one that links to the DLL.

2. The SYSTEM directory.  (c:\windows\system or something similar)

3. The directories on the PATH environment variable.  Since you are on win98
you probaly have a c:\autoexec.bat that sets this variable.  If you edit
this you will need to reboot for it to take effect globally.

Perhaps the easiest is to copy the various gtk DLLs to the directory where
the _gtk.pyd file is located.  Perhaps better is to add the path where they
are already to the PATH and reboot.
