Not a matter of allowed.  .dll.so libraries don't export the windows
functions as elf symbols, so you need winemaker to resolve them.

Why do you want to?  What do you have against winelib?
Do you want to distribute something without dragging all of winelib
along?  I guess yo can limit the winelib dll's you need, but remember
you will need wine (and at least the winelib dll's it links to
directly) ("ldd /usr/local/bin/wine")) to ... What is it you are trying
to do?  This is getting too abstract for me.

This looks like what you would get with the --wrap option of winemaker,
I think.  Are you planning to write the implementation of do_it and
compile it with lcc-win32 or something, or do you have a windows dll
lying around you want to use?

If you look at the little scripts that bear the names progman, regedit,
and so on, you will see that they call wine to load and execute
progman.exe.so....

As it said in the snippet you quoted to start this, a wine dll is a
win32 dll encapsulated inside a Unix library.

I have a little winelib program I will use to send this that reads
Unix stdin and adds what it reads to a windows storage object mailbox
file.  If for some reason it can't, it logs the error to the Unix
syslog.
