AFAIK if it is used, it's rather useless, because the same effect
- exporting a function - can be done by the *.def file.
This isn't needed on *ix because everything is exported by default.
Variables like color_black are a special case, at least on Win32.
They not only need to be *exported* but *imported* too.
Otherwise they wont get initialized correctly, in DIA case all
colors remain zero - simply drawing black on black ...
BTW: they same code is needed in libgimp, but there it is
called GIMPVAR.
