the definition of the long is right, but the suffix is different. Win64 
platform
is LLP64 and not LP64, which means that 64bit are used for both "long 
long" type
and "pointers", everything other is the same as in the 32bit arch. Ditto 
for Linux64 which is LP64 and not
LLP64, i.e. the type "long" and "pointer" are at 64bit, while all the 
rest is as in 32bit arch.
