I believe Zack was speaking in favor of canonicalizing the -windows-*
names. But if he wasn't, then consider that the recently introduced
``triplets'' actually duplicate existing ones -- and by doing so,
constitute a change to the canonicalized names produced by config.sub.
So now Emacs will need to accept:
# MinGW64
x86_64-*-* )
case "${canonical}" in
*-mingw* )
*-windows-gnu )
in addition to just *-mingw*. Analogous modifications to configure must
even be retroactively effected on previous releases of Emacs, since we
recommend that config.sub and config.guess always be updated to their
latest versions.
