# Any file that needs the FreeBSD overrides that are in
# include/os/freebssd/spl/XXX needs to have these added to
# CFLAGS_EARLY.file.c. In general, we try to build out of the OpenZFS tree
# unaltered. There's a problem, though, that since we're building for a
# standalone environment that's neither userland nor kernel, we sometimes need
# special code and that's handled by the 'nested' includes where we either setup
# something just-so before we include the include/XXX file, or if we need to
# tweak something defined in that file.
