- these are defined in C99 (wcsto[ui]max) and SUSv3.
- these implementations are written by sigsegv@s25.xrea.com,
derived from NetBSD's wcstol/wcstoul.
- I just added some comments.
to <sys/types.h> and <sys/stdint.h>.
* Add a new C99 <stdint.h> header, which provides integer types of
explicit width, related limits and integer constant macros.
* Extend <inttypes.h> to provide <stdint.h> definitions and format
macros for printf() and scanf().
* Add C99 strtoimax() and strtoumax() functions.
* Use the latter within scanf().
* Add C99 %j, %t and %z printf()/scanf() conversions for
intmax_t, pointer-type and size_t arguments.
