-# since this reason is a little short on information, and I'm having
-# trouble with subdirectory builds happening before the current

-# (b) when SUBDIRS is empty,
-#     for each "multi-way-target" <t>

-# 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
