/* VC6-only fallback for the C99 <stdint.h> header.
 *
 * Visual C++ 6.0 (_MSC_VER 1200) predates C99 and ships no <stdint.h>. This
 * project-local header is found ahead of any system <stdint.h> only because
 * compat/msvc600 is placed first on the VC6 probe scripts' include path
 * (scripts/vc6-probe.sh, scripts/vc6-probe-core.sh, scripts/vc6-probe-
 * pythoncore-frontier.sh); it is never installed anywhere a standards-
 * conforming compiler's own <stdint.h> would be found instead, so it never
 * shadows a real one.
 *
 * First consumer: cpython/Modules/_blake2/impl/blake2.h and
 * blake2-impl.h, which use only uint8_t, uint32_t, and uint64_t (verified
 * by grepping every fixed-width identifier used across Modules/_blake2/,
 * including the blake2b/blake2s/*-ref.c reference implementations and
 * clinic-generated wrappers: no int8_t/int16_t/int32_t/int64_t or intptr_t/
 * uintptr_t appear anywhere in that tree). `size_t` is used too, but that
 * already comes from <stddef.h>, which VC6 has natively.
 *
 * compat/msvc600/inttypes.h already defines exactly these typedefs (plus
 * the PRI* macros CPython's own Include/pyport.h needs from a real C99
 * <inttypes.h>) for this same VC6 target. Rather than re-declaring
 * uint8_t/uint32_t/uint64_t a second time under a second include guard
 * (which would risk a duplicate-typedef error in any translation unit that
 * ends up including both this header and <inttypes.h>, e.g. anything that
 * pulls in both Python.h and a <stdint.h>-using third-party header like
 * blake2.h), this header just forwards to it. inttypes.h's own include
 * guard makes this forwarding idempotent no matter which of the two headers
 * a given translation unit reaches first.
 *
 * Width assumptions (all already relied upon by inttypes.h and unchanged
 * here): uint8_t = unsigned char (1 byte), uint32_t = unsigned long
 * (4 bytes on Win32/ILP32), uint64_t = unsigned __int64 (VC6's non-standard
 * 64-bit extension, 8 bytes). These match the sizes BLAKE2 requires.
