Although that's true for much of Gnulib, many Gnulib modules would work just 
fine on such hosts.

gl_STDINT_H's tests of uint8_t all depend on UINT8_MAX being defined, which is 
not true on hosts lacking uint8_t, so stdint won't provide uint8_t merely 
because a standard-conforming stdint.h lacks uint8_t. At least, that's the 
intent of gl_STDINT_H.

Admittedly this issue is pretty esoteric nowadays.

We could finesse all this by simply using char instead of uint8_t, since the 
values in question are all in the range 0..127 on all platforms we know about.
