[PATCH cygport 2/2] Fixup __version_at_least a bit

[Jon Turney]

Use the variables we've made containing the separated version
components, rather than an undefined one

[PATCH cygport 1/2] meson: use auto-features option

[Jon Turney]

This option added in 0.47 [1], is intended to be used by distribution
packaging to ensure that features for a package are explicitly
configured. (e.g see discussion at [2])

(Note that features are a relatively recent meson feature and thus
aren't used by some packages)
