even adding these together, i don't see any problem. the ultra-paranoid
ones can simply delete include/ (and configure.exe) from the extracted
source tree, and thus start as if they got the sources from git (as
projected now, they'd need a "git init" to trick the build system into
believing it's a real git build. that could be rectified by adding a
-git-build option to configure).
