[C99] Fix definitions of INTn_C macros #133916

AaronBallman · 2025-04-01T14:18:55Z

C99 introduced macros of the form INTn_C(v) which expand to a signed or unsigned integer constant with the specified value v and the type int_leastN_t. Clang's initial implementation of these macros used token pasting to form the integer constants, but this means that users cannot define a macro named L, U, UL, etc before including <stdint.h> (in freestanding mode, where Clang's header is being used) because that could form invalid token pasting results. The new definitions now use the predefined __INTn_C macros instead of using token pasting. This matches the behavior of GCC.

Fixes #85995
