Bug ID: 42098
Summary: __CHAR16_TYPE__ and __CHAR32_TYPE__ are defined on
MacOS but they don't actually work
Product: clang
Version: unspecified
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: release blocker
Priority: P
Component: C
Assignee: [email protected]
Reporter: [email protected]

MacOS's SDK does not include the uchar.h header, and since these macros are
defined by the compiler the macro check doesn't work, breaking my code.
I filed a bug report with Apple about it, bug #51322492 but they don't seem to
care.
Example code to get the bug to appear:
#ifdef __CHAR32_TYPE__
typedef char32_t UTF32;
#else
typedef uint_least32_t UTF32;
#endif /* __CHAR32_TYPE__ */
