While <stdint.h> is only part of C99 but not of ISO C++ the
tr1 extension defines <stdint.h> and <cstdint>. The later
puts the types in the std:: namespace <stdint.h> provides them
in the global  namespace (like C99).

If we want to realy on plain ISO C++ without extensions the
answer is simple: Don't use any of those headers or reimplement it.
