I figured that platform-dependence issues were a
barrier to 64-bit integer support. I'm not familiar
with Boost's platform philosophy. In general, is a
feature only supported if it works on every platform?
Or does Boost insert platform-specific switches to
implement features whenever possible? 64-bitness
seems to be a good general addition to Boost's integer
library, if it's not a great amount of effort.
