+#
+# This makefile is designed to be run in one of three ways:
+#
+#	make clean
+#	make depend
+#	make build
+#	make installsrc
+# This is the most rigorous way to rebuild the source tree.
+# The first two steps will clean the source tree and remake the dependencies.
+# The `make build' will compile and install the libraries and the compiler
+# twice before building the rest of the sources.  The `make installsrc' will
+# then install the remaining binaries.
+#
+#	make libthenall
+#	make installsrc
+# The `make libthenall' will compile and install the libraries, compile
+# and install the compiler and then compile everything else.  Note,
+# however, that the libraries will have been built with the old compiler.
+# The `make installsrc' will then install the remaining binaries.
+#
+#	make all
+#	make install
+# The `make all' (the default) will compile everything, and install
+# nothing.  The `make install' will then install everything.
+#
+# 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
