32// The behavior of many of the functions in the <ctype.h> header is dependent
33// on the current locale. But almost all uses of these functions are for
34// locale-independent, ASCII-specific purposes. In WebKit code we use our own
35// ASCII-specific functions instead. This header makes sure we get a compile-time
36// error if we use one of the <ctype.h> functions by accident.
37
38// this breaks compilation of <QFontDatabase>, at least, so turn it off for now
39// Also generates errors on wx on Windows, presumably because these functions
40// are used from wx headers. On GTK+ for Mac many GTK+ files include <libintl.h>
41// or <glib/gi18n-lib.h>, which in turn include <xlocale/_ctype.h> which uses
42// isacii().
