#
# This makefile is designed to be run as:
#       make build
#       make installsrc
# The `make build' will compile and install the libraries
# before building the rest of the sources. The `make installsrc'
# will then install the remaining binaries.
#
# It can also be run in the more conventional way:
#       make
#       make install
# The `make' will compile everything without installing anything.
# The `make install' will then install everything. Note however
# that all the binaries will have been loaded with the old libraries.
#
# C library options: passed to libc makefile.
# See lib/libc/Makefile for explanation.
# HOSTLOOKUP must be either named or hosttable.
# DFLMON must be either mon.o or gmon.o.
# DEFS may include -DLIBC_SCCS, -DSYSLIBC_SCCS, both, or neither.
#

DFLMON=mon.o
DEFS= -DLIBC_SCCS
