It's better to keep the discussion on the mailing list, so that others
can benefit (and help) also.

Until someone figures out the underlying cause of the "unable to map"
error for cygSDL*.dll, my only suggestion is to try to work around the
problem as I did for gimp: avoid using SDL. In your case, I think SDL
is brought in via the package libwx_gtk3u3.0_0. If you look at the
source for that package, you'll see that it uses the configure option
--with-sdl. So you could try to rebuild it without that option.

Two things:
1. --with-sdl occurs twice in the .cygport file. Be sure to remove both
occurrences.
2. Running 'cygport wxWidgets3.0.cygport prep/compile/test/install' is
not enough. The 'install' part of this uses a destination directory
'inst' in the work directory created by cygport. You also have to run
'cygport wxWidgets3.0.cygport package', which creates several package
tarballs in the 'dist' directory. The best way to proceed from there is
explained in
https://cygwin.com/package-server.html
under "Creating an overlay Cygwin package server". If you use this
method, then you'll have to bump the release number in the .cygport file
so that setup will recognize that there's a new version of libwx_gtk3u3.0_0.
