[Emacs-diffs] master 2f9d547: Port --enable-gcc-warnings to clang 3.7.0

[Paul Eggert]

branch: master
commit 2f9d547329e8459965692383c5a95d41b7035726
Author: Paul Eggert <address@hidden>
Commit: Paul Eggert <address@hidden>

    Port --enable-gcc-warnings to clang 3.7.0
    
    * configure.ac: Add -Wno-tautological-compare to avoid bogus
    warnings about 0 <= rlim.rlim_max.  Remove flags that no longer
    seem to be needed, at least in Fedora 23 x86-64.
