25  * Definition of C99's exact-width integral types for JTie.
26  *
27  * JTie has pre-defined type mappings for the C99 exact-width type aliases:
28  * int8_t, uint8_t, ... int64_t, uint64_t, which are a more natural fit for
29  * Java than the native, integral C types, char ... long long,
30  *
31  * Unfortunately, the C99 <stdint.h> file is not provided by some C/C++
32  * compilers. (It's a crying shame. For instance, MS Visual Studio
33  * provides <stdint.h> not until VS2010.) Therefore, this header deals in a
34  * single place with the presence or absence of the <stdint.h> file.
35  *
36  * While JTie applications (like NDB JTie) may have their own type aliases
37  * for exact-width types, it is preferrable not use these as the basis for
38  * JTie's implementation and tests itself -- for platform testing has proven
39  * much easier with a self-contained, standalone-compilable and -testable
40  * JTie unit tests, where problematic patterns can be readily identified.
41  * Hence, applications with their own, non-stdint-based exact-width type
42  * definitions should add and use corresponding JTie type mapping aliases.
