Interesting idea - maybe we could have a library exposing NSUserDefaults
with a simple C interface.

Then WindowMaker could use this C library (optionally I suppose, if
compiled with support for it) to use native GNUstep user defaults
natively.

If the library is not available, they'd use some sort of built-in fallback
which does something similar in pure C.
