// Minimal stdint.h for the W65816 runtime.  Standalone (does not
// include the host clang's stdint.h, which pulls in glibc headers
// and breaks the build).  Sizes per the W65816 backend's view:
//   char     = 8 bits
//   short    = 16 bits
//   int      = 16 bits
//   long     = 32 bits
//   long long = 64 bits
