+# 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
+#
+# There may be other macros in mdb.c of interest. You should
+# read mdb.c before changing any of them.
