# the official documentation.
#
# Note that we "prefix" them to what might have been specified by the user so
# that it is possible to override the defaults by specifying them as =0 (it's
# also the reason we use cc.* instead of c.*, the former comes first).
#
# PREUPDATE_HOOK is required by SESSION
#
# -DSQLITE_ENABLE_SESSION=1 removed for now due to bug in 3.18.0.
#
# Note that if disabling any previously-released features, then will need to
# increment abi_major.

  # want them to be linked in the same way as -lc (e.g., the user will have to
  # specify -static to force static linking and so on).
