/* Prevent the users of safe-ctype.h from accidently using the routines
|

from ctype.h. Initially, the approach was to produce an error when
|
|
detecting that ctype.h has been included. But this was causing
|
|
trouble as ctype.h might get indirectly included as a result of
|
|
including another system header (for instance gnulib's stdint.h).
|
|
So we include ctype.h here and then immediately redefine its macros. */
