make portable stdint.h from boost code

[nobody]

There appears to be an industry-wide need for a good,
portable stdint.h library, compatible with the C99
standard.  boost.org has the knowledge to create such a
header, based on their current stdint.hpp header and
associated code.  However, what is needed is a
C-compatible version that could be used in any environment.

boost.org would be doing developers a big favor if it
could adapt its existing stdint.hpp header to a
C-compatible C99 compliant stdint.h header.

I'm going to close this down for two reasons:

• We don't support C.
• Many platforms now ship with pretty good stdint.h implementations anyway.
