One possibility might be to not define the types at all, unless the
gnulib application explicitly asks for them. Lots of applications want
uint32_t, and I imagine a lot fewer have any need for int_fast*_t.
Yes. For this reason, libunistring installs a trimmed-down version of
gnulib's stdint.h, that defines only the int{8,16,32}_t types and not
all the rest (int64_t, int_least*_t, int_fast*_t, etc.). [1]
