[Insight-developers] Nonportable Code

[Tom Vercauteren]

Hi Sean,

Yes c++0x will have cstdint. It is already in boost.

In the meantime we might want to rely on pstdint.h (a portable stdint):

See wikipedia for more information
http://en.wikipedia.org/wiki/Stdint.h

But it looks like a large change to do right before the release.
