I'm not super happy with the patch. First, I'm not at all sure we can 
safely assume _GLIBCXX_USE_C99_STDINT_TR1 is always defined here, 
because otherwise the <cstdint> boils down to nothing and your patch 
doesn't work. Please double check.

Besides these boring configury issues, I don't like the idea of using 
the max of uint16_t for an unsigned int variable. Maybe it happens to 
work on the actual targets supported now, but why not using directly an 
uint16_t variable? In any case, if uint16_t isn't actually available per 
the above issue, n or m > n instances of it are equally wrong ;)

Paolo.
