-# 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_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.
