# Configuration. The compiler options must enable threaded compilation.
#
# Preprocessor macros (for CPPFLAGS) of interest...
# Note that the defaults should already be correct for most
# platforms; you should not need to change any of these.
# Read their descriptions in mdb.c if you do:
#
# - MDB_USE_POSIX_MUTEX, MDB_USE_POSIX_SEM, MDB_USE_SYSV_SEM
# - MDB_DSYNC
# - MDB_FDATASYNC
# - MDB_FDATASYNC_WORKS
# - MDB_USE_PWRITEV
# - MDB_USE_ROBUST
#
# There may be other macros in mdb.c of interest. You should
# read mdb.c before changing any of them.
