makefile

早期freebsd实现

CPP = $(CC) -E
MAKE = make  # BSD doesn't have it as a default.
#Note: an alternative is  CPP = /lib/cpp

all: xmakefile doall

doall:
	$(MAKE) $(MAKEOVERRIDES) -f xmakefile ${MFLAGS} all

#This is used in making a distribution.
#Do not use it on development directories!

# If you have a problem with cc -E here, changing
# the definition of CPP above may fix it.
