Strictly speaking you're not allowed to ask that question... it's a secret 
:-)

The idea is that int8_t is whatever platform-dependent type has 8-bits and 
is signed.

But since you ask, it's "signed char" on any platform you're ever likely to 
encounter.  You should never make any assumptions about the actual types of 
the int#_t typedefs though - some of them really are "unmentionable" 
platform dependent types on some platforms - but take a look at 
boost/cstdint.hpp for the details.

HTH, John.
