Subject: Ensure we always have a complete keymap
X-Git-Tag: xkbcommon-0.2.0~752
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=57b551a4189c7c9d9dccc816c43b4c18e1111392;p=platform%2Fupstream%2Flibxkbcommon.git

Ensure we always have a complete keymap

Refuse to compile without keycodes + compat + types + symbols.
