The split-tree putback broke the use of ParallelMake to build the
tree, by introducing some variable definitions of the form
FOO = \
a \
b \
c \
i.e., the last line should not end in a backslash.
dmake and /usr/ccs/bin/make do not choke on these variable
definitions, but they really are broken and need to be fixed.
