I spoke too soon. The reason intptr_t and uintptr_t were omitted was because 
they are not required by C99, and hence not required by TR1.

So we should discuss this further before applying Maxim's patch.

On one hand, we may not want Boost code to use a feature that may not be 
present.

OTOH, if virtually all modern C++ compilers do support an integral type 
large enough to hold a pointer, why not supply intptr_t and uintptr_t?

One possibility is to go ahead and supply intptr_t and uintptr_t, and also 
supply a BOOST_HAS_INTPTR_TYPES (or perhaps BOOST_NO_INTPTR_TYPES) 
configuration macro.

Views? Comments?
