# serial 2
# From Paul Eggert.
# Some versions of BeOS define mbstate_t to be an incomplete type,
# so you can't declare an object of that type.
# Check for this incompatibility with Standard C.
# Include stdio.h first, because otherwise this test would fail on Linux
# (at least 2.2.16) because the `_XOPEN_SOURCE 500' definition elicits
# a syntax error in wchar.h due to the use of undefined __int32_t.
