If I were you I wouldn't bother with a 21.2 version. It would
only be used by people who want sound but don't want to use 21.3.50
and yet are willing to get the source code and recompile. I expect
this group of people to be pretty small (especially on w32).

The main target should be 21.3.50 so it would be better not to add
unrelated cruft in it.

How about not adding a new file w32sound.c but instead adding the
corresponding code to sound.c (and of course wrap things in
#ifdef WINDOWSNT (or _WIN32, I don't know what is what: most of
the Emacs C code I've seen seems to be using WINDOWSNT)).
This way the parsing and other such things will be shared.
Oh, and please just send the plaintext patch as attachment,
so we don't need to save/unpack the zip archive to read it.
