// stdint.h is provided by Clang, but it dispatches to libc's stdint.h.  As a
// result, using stdint.h here would pull in Darwin module (which includes
// libc). This creates a dependency cycle, so we can't use stdint.h in
// SwiftShims.
// On Linux, the story is different. We get the error message
// "/usr/include/x86_64-linux-gnu/sys/types.h:146:10: error: 'stddef.h' file not
// found"
// This is a known Clang/Ubuntu bug.

// Clang has been defining __INTxx_TYPE__ macros for a long time.
// __UINTxx_TYPE__ are defined only since Clang 3.5.
