branch: master
commit efe42c2b63de8ef5da3e6cb5f576fb5f6eea0281
Author: Stefan Monnier <monnier@iro.umontreal.ca>

    * lisp/progmodes/antlr-mode.el: Fix bootstrap failure
    
    (antlr-mode): Remove compatibility code with older CC-mode.
    This somehow appears to fix the error:
    
        In antlr-mode:
        progmodes/antlr-mode.el:2426:20: Error: `c-init-language-vars' defined
            after use in (c-init-language-vars) (missing `require' of a library
            file?)
        progmodes/antlr-mode.el:2427:26: Warning: c-init-language-vars called
            with 0 arguments, but requires 1
    
    No idea what caused the error to appear after the previous patch either.
