Comment at: clang/lib/Headers/float.h:92-93 -#if __STDC_VERSION__ >= 199901L || !defined(__STRICT_ANSI__) || __cplusplus >= 201103L +#if __STDC_VERSION__ >= 199901L || !defined(__STRICT_ANSI__) || \ +__cplusplus >= 201103L || defined(_AIX) && defined(_ALL_SOURCE) # define DECIMAL_DIG __DECIMAL_DIG__ I understand why `_ALL_SOURCE` matters when `__STDC_HOSTED__` does not evaluate to 0, but the general logic of the file is that platform extensions are not present for freestanding. The interfaces injected via `_ALL_SOURCE` are platform extensions.
