[Owen Taylor <otaylor src gnome org>]

    Remove -Wfloat-equal
    
    While -Wfloat-equal warns on dubious constructs, it also warns on
    valid constructs, and there is no way to suppress the warning.
    
    In particular, it's currently warning for every single file because of
    JS_CANONICALIZE_NAN() in the xulrunner headers.
