Don’t conditionalize declarations of ldiv_t, lldiv_t, __gwchar_t.
The declarations of ldiv_t, lldiv_t, and __gwchar_t are all wrapped in __foo_t_defined conditionals, despite there being only one header in glibc that declares them. I checked codesearch.debian.net and only found one other program that refers to the __foo_t_defined conditionals: u-boot provides its own definition of ldiv_t if __ldiv_t_defined is not defined by stdlib.h. I conclude that the conditionals are not necessary, but the definitions of __ldiv_t_defined and __lldiv_t_defined should be preserved. * stdlib/inttypes.h: Unconditionally define __gwchar_t. Don’t define ____gwchar_t_defined. * stdlib/stdlib.h: Unconditionally define ldiv_t. Condition lldiv_t only on __USE_ISOC99.
