/* This is a compatible replacement of the standard C library's <ctype.h>
with the following properties:
- Implements all isxxx() macros required by C99.
- Also implements some character classes useful when
parsing C-like languages.
- Does not change behavior depending on the current locale.
- Behaves properly for all values in the range of a signed or
unsigned char.
To avoid conflicts, this header defines the isxxx functions in upper
case, e.g. ISALPHA not isalpha. */

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. */
