# For the FreeBSD auto patching mechanism and compatibility environment
# setup, original FreeBSD sources a put into a FreeBSD subdirectory.
# If a file with the same name, but suffix ".patch" is in that directory,
# that patch will be applied before use.
#
# The FBSDMDSRCS, FBSDMISRCS, FBSDORIGHDRS and FBSDSRCS variables must be set,
# and bracketed by .include of Makefile.fbsd_begin and Makefile.fbsd_end
#
# Set up dependencies between the FreeBSD source (in a FreeBSD subdirectory)
# and a file with a -fbsd.x suffix (where x is 'c' or 's').  The suffix
# rules will then compile the file with the simulate FreeBSD environment.
