Actually, the default pacman/makepkg configuration is indeed gz, at
least in the sense that that is what etc/makepkg.conf.in will be
configured with unless you define your own:
./configure --with-pkg-ext --with-src-ext
Arch Linux does not ship with the stock pacman.conf and makepkg.conf,
though. We set distribution defaults independent of the distro-agnostic
pacman.git sources; these distribution defaults include the use of xz
over gzip for compression.
I'm not sure what would make an appropriate default, since unlike many
other makepkg.conf settings the fallback when unspecified is to carry on
as if '' is a plausible answer when it isn't, and it *should* raise a
fatal error I guess. I'll write a lint check for that...
Perhaps it would make sense to have the manpage depend on how
--with-pkg-ext --with-src-ext were used. Although Arch Linux would still
then be calling out gz.
