[ELPA Syncer]

branch: externals/compat
commit 68fdf2d41bda18cdec64b78e2391adde95a05bdb
Author: Daniel Mendler <mail@daniel-mendler.de>

    Enable byte compilation warnings also for Emacs master
    
    We follow upstream improvements closely and profit earlier from
    additional byte compiler warnings.
