Note that this particular issue is easy to fix, which would allow the 
header to be used with older compilers, not just for building glibc 
(although it may not be much use with them, given lack of support for the 
Unicode string syntax).  The types in question are required to match 
uint_least16_t and uint_least32_t, and with glibc those are always 
unsigned short int and unsigned int respectively - so those are safe 
fallback definitions when the C compiler does not predefine those macros.
