Summary:                    test_INT_C.c and test_INT_CXX.cxx fail to compile
due to broken PRIxNN macros
Description: 
Building CMake git nightly on AIX 4.3 yields these errors:

In file included from .../CMake/Utilities/KWIML/test/test_INT_C.c:14:
.../CMake-build/Utilities/KWIML/test/test_INT_format.h: In function
`test_INT_format':
.../CMake-build/Utilities/KWIML/test/test_INT_format.h:106: `hi' undeclared
(first use in this function)
.../CMake-build/Utilities/KWIML/test/test_INT_format.h:106: (Each undeclared
identifier is reported only once
.../CMake-build/Utilities/KWIML/test/test_INT_format.h:106: for each function it
appears in.)

This platform has a long-standing issue with broken PRIxNN format macros in
/usr/include/inttypes.h. An excerpt:

    #define PRId8           %hd
    #define PRId16          %hd
    #define PRId32          %d
    #if defined(__64BIT__)
    #define PRId64          %ld
    #else
    #if defined(_LONG_LONG)
    #define PRId64          %lld
    #endif
    #endif

On the Autoconf side, Gettext has an m4 macro gt_INTTYPES_PRI that checks for
this:

    https://gnunet.org/svn/Extractor/m4/inttypes-pri.m4

CMake could probably avoid the use of inttypes.h on this system altogether; the
above files compile correctly with -DcmIML_INT_NO_INTTYPES_H. Either that, or it
needs to know to use its own format-string macros instead of the system's.
