Follow-up Comment #1:

Hi Frank; the 3.81 behavior is correct.  The POSIX spec for make says:

When an escaped <newline> is found in a command line in a makefile, the
command line shall contain the backslash, the <newline>, and the next line,
except that the first character of the next line shall not be included if it
is a <tab>.

See the GNU make manual subsection "Splitting Command Lines" (node "Splitting
Lines"), in section "Command Syntax", chapter "Writing the Commands in Rules",
for details.

We are discussing adding a ".ONESHELL" feature for the next version of GNU
make; if we do that then this could be used to get the kind of behavior you're
looking for.
