This will work well enough for POSIX systems, but will fail miserably on
Windows systems. Most Windows users do not develpment tools installed,
and would have a hard time to find a C compiler producing binaries with
the correct ABI, and the other required build tools and dependencies.

Users should not have to deal with any of this in order to use libraries
that emacs uses via an FFI. They might just be able to deal with loading
a lisp package and adding a DLL to somewhere visible on the PATH, but
even that is too complicated for many (they expect installer programs to
do this work automatically).
