inttypes: modernize

[Bruno Haible]

A small modernization. A preparation for the next patch.


2012-01-05  Bruno Haible  <address@hidden>

        inttypes: Modernize.
        * lib/inttypes.in.h (strtoimax, strtoumax): Use the C++ safe idioms.
        * modules/inttypes-incomplete (Depends-on): Add snippet/c++defs.
        (Makefile.am): Update inttypes.h rule.
