// The behavior of many of the functions in the <ctype.h> header is dependent
// on the current locale. But almost all uses of these functions are for
// locale-independent, ASCII-specific purposes. In WebKit code we use our own
// ASCII-specific functions instead. This header makes sure we get a compile-time
// error if we use one of the <ctype.h> functions by accident.

// this breaks compilation of <QFontDatabase>, at least, so turn it off for now
// Also generates errors on wx on Windows, presumably because these functions
// are used from wx headers. On GTK+ for Mac many GTK+ files include <libintl.h>
// or <glib/gi18n-lib.h>, which in turn include <xlocale/_ctype.h> which uses
// isacii().
