Using <inttypes.h> is more portable than <stdint.h> since it was 
defined earlier.

It is easy to conflate the compiler with the system header files.  On 
Unix type systems, often inttypes.h or stdint.h comes from system 
header files rather than the compiler.  For Microsoft Windows, the 
header likely comes from the SDK, which is mostly independent of the 
OS version.

It all comes down to if you choose to abandon a portion of potential 
users (typically non GNU-Linux) for the sake of convenience.  I have 
not decided to do that yet since it has not proven difficult to 
support old compilers and systems even dating from the late '90s.
