The requirement to include the copyright notice with
binary-only distributions could be removed, just
requiring the copyright notice with source
distributions; a lot of BSD-style licenses do that
(e.g. zlib license).
The license which ReWind uses (often called the
MIT/X11 license) is a possibility:
Copyright (c) <year> <copyright holders>
Permission is hereby granted, free of charge, to any

without limitation the rights to use, copy, modify,

the Software is furnished to do so, subject to the
The above copyright notice and this permission notice
shall be included in all copies or substantial
portions of the Software.
THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF

AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING

USE OR OTHER DEALINGS IN THE SOFTWARE.
The latter seems reasonable, as credit must be given
if substantial portions of the software are used (e.g.
in another Win32 API implementation), but applications
built with w32api wouldn't use a substantial portion
of the software (only including a handful of function
declarations and data structures) so binaries built
with Mingw would not need to include the copyright
notice if this license were used.
As you say though, public domain might make more
sense, something akin to the Allegro developers'
"Gift-ware" license perhaps (rewriting it somewhat to
refer to Mingw and w32api rather than Allegro and
Allegro is gift-ware. It was created by a number of
people working in cooperation, and is given to you
freely as a gift. You may use, modify, redistribute,
and generally hack it about in any way you like, and
you do not have to give us anything in return.
However, if you like this product you are encouraged
to thank us by making a return gift to the Allegro
community. This could be by writing an add-on package,
providing a useful bug report, making an improvement
to the library, or perhaps just releasing the sources
of your program so that other people can learn from
them. If you redistribute parts of this code or make a
game using it, it would be nice if you mentioned
Allegro somewhere in the credits, but you are not
required to do this. We trust you not to abuse our
and their disclaimer:
"I do not accept responsibility for any effects,
adverse or otherwise, that this code may have on you,
your computer, your sanity, your dog, and anything
else that you can think of. Use it at your own risk."
Well, the disclaimer probably needs to be a bit more
formal :-) ; the disclaimer from the MIT/X11 license
could be used for example.
