Hello from libgit2, where we borrowed your xdiff a few years ago and
have watched as we both hacked on it independently.  (For us, mostly it
was around tightening some things up around warnings and signed/unsigned
mismatches.)  However, we'd love to share a common xdiff implementation,
and we're happy if git is the home for that.

The next patch adds an indirection point, `git-xdiff.h`, that contains
the git-specific functionality in xdiff.  This keeps the core of xdiff
to standard functions.  Other xdiff users, like libgit2, can specify
their own compatibility functions in this header file.

I hope that this allows us to make progress on a common xdiff; we'd love
to go back to building it without warnings, but we'd like to not do that
in isolation.

Cheers-
