Include inttypes.h (or cintypes for C++) instead of stdint.h

From autoconf manual, section 5.6.1 Portability of Headers, says:

"""
The C99 standard says that inttypes.h includes stdint.h, so there's no
need to include stdint.h separately in a standard environment. Some
implementations have inttypes.h but not stdint.h (e.g., Solaris 7),
but we don't know of any implementation that has stdint.h but not
inttypes.h.
