Re: [PATCH][BZ 17979][BZ 17721] Fix issues with sys/cdefs.h and uchar.h when using non-gcc compiler.

[Dwight Guth <dwight.guth@runtimeverification.com>]

Alright, fair enough. So the solution you want to see is to move
stdint.h out of sysdeps, move the definition of uint_least16_t and
uint_least32_t to a definition of __*_t in bits/stdint.h, and then
define uint_least16_t, uint_least32_t, char16_t, and char32_t on the
basis of the __*_t types? Or is this overkill given that we are
assuming that stdint.h doesn't need to be system-specific? Which would
you prefer?
