CrtLibSupport.h defines SIZE_MAX and UINTPTR_MAX as 32-bit constants. The UINTPTR_MAX definition was controlled by "#if (UINT_MAX > 0xFFFFFFFFUL)" (can never be true), and SIZE_MAX was just hard-coded to 0xFFFFFFFF. The fix cannot just use MAX_UINTN because that isn't usable in preprocessor conditions. Instead, define SIZE_MAX and UINTPTR_MAX based on CPU. Also correct intptr_t, which was a typedef of the unsigned UINTN. The neighbouring ptrdiff_t and ssize_t already use INTN. PlatformTpmNullLib casts a pointer to intptr_t in NVMem.c, so the signedness matters. Nothing in TcgTpmPkg currently evaluates SIZE_MAX or UINTPTR_MAX, so this does not change the built output today; it corrects definitions that are wrong on 64-bit targets and keeps the header identical to the CryptoPkg copy, which is fixed by a separate patch. Tested by building TcgTpmPkg/TcgTpmPkg.dsc with GCC for AARCH64 (the only architecture the package supports). It builds cleanly before and after. Signed-off-by: Doug Cook <dcook@microsoft.com>
