# Regression tests for the narrow VC6 compat/msvc600/stdint.h shim.
#
# Skipped (not failed) when Wine + MSVC600 are unavailable, matching the other
# VC6 probe test scripts. The live check is compile-only: it verifies that the
# fixture using representative uint8_t/uint32_t/uint64_t load/store/rotate
# patterns (the exact subset cpython/Modules/_blake2/impl/blake2-impl.h uses)
# reaches cl.exe exit 0, and that <stdint.h> and <inttypes.h> can both be
# included in the same translation unit without a duplicate-typedef error.
#
# Usage: scripts/vc6-probe-stdint.test.sh
