[Emacs-diffs] master 9dc6e93 1/2: Explicitly require C11 or C++11 in emacs-module.h

[Philipp Stephani]

branch: master
commit 9dc6e93b77ce0d920771060756e65779751fd5f7
Author: Philipp Stephani <address@hidden>
Commit: Philipp Stephani <address@hidden>

    Explicitly require C11 or C++11 in emacs-module.h
    
    We already implicitly require them by including stdbool.h.  Just make
    the error message a bit clearer, and remove an unnecessary version
    comparison.
