-# Recursive stuff

+# Pre-compute the list of sources so we don't have to do this
+# multiple times. See paths.mk.
-# Here are the diabolically clever rules that
-#
-# (a) for each "recursive target" <t>
-# propagates "make <t>" to directories in SUBDIRS
-#
-# (b) when SUBDIRS is empty,
-# for each "multi-way-target" <t>
-# calls "make way=w <t>" for each w in $(WAYS)
-#
-# This has the effect of making the standard target
-# in each of the specified ways (as well as in the normal way
+PRE_SRCS := $(ALL_SRCS)
-# Controlling variables
-# WAYS = extra (beyond the normal way) ways to build things in
-# SUBDIRS = subdirectories to recurse into
-
-# No ways, so iterate over the SUBDIRS
-
-# note about recursively invoking make: we'd like make to drop all the
-# way back to the top level if it fails in any of the
-# sub(sub-...)directories. This is done by setting the -e flag to the
-# shell during the loop, which causes an immediate failure if any of
-# the shell commands fail.
-
-# One exception: if the user gave the -i or -k flag to make in the
-# first place, we'd like to reverse this behaviour. So we check for
-# these flags, and set the -e flag appropriately. NOTE: watch out for
-# the --no-print-directory flag which is passed to recursive
-# invocations of make.
-#
-# NOTE: Truly weird use of exit below to stop the for loop dead in
-# its tracks should any of the sub-makes fail. By my reckoning,
-# "cmd || exit $?" should be equivalent to "cmd"
