The whole problem here is that it simply does not work to include the
stdint.h C99 header into the C++ program.
The clean solution would be to #include <cstdint> instead, but that
means with the g++ compiler to pass the switch -std=c++0x otherwise this
header is not supported.
Maybe a less intrusive way is to simply check for __WORDSIZE == 32 (or
64) since that is defined as far as I can see.
