Thanks for the C99 reference. Do you happen to know when it was added to C++?

For the record, it became fairly common with C++ world in the early 'naughts'
to abstract hardware and OS sizes away when more code was going from being
used only on 32-bit OSs to also being used on 64-bit OSs.  And being able to
specify the width of integers was a big help for portable code.
