    Get --enable-gcc-warnings working again. · 2bafb7c4
    Paul Eggert authored
    The recent changes to configure.ac removed the transliteration of
    -I to -isystem in CFLAGS, which is needed for --enable-gcc-warnings.
    Bring this back while keeping the spirit of the recent changes.
    * configure.ac (edit_cflags): Restore this shell var, and put it
    at the top level, where it'll be useful when emacs-24 is next merged.
    (EMACS_CHECK_MODULES): New macro.  All uses of PKG_CHECK_MODULES
    changed to use it.
