I stand corrected. The simple demo of this feature would be:
foo: .SILENT
VARIABLE=value
echo $${VARIABLE}
BTW, I have found the relevant info in the section 2.2 of the
/usr/share/doc/psd/12.make/ paper:
: Because all the commands are given to a single shell to execute,
: such things as setting shell variables, changing directories, etc.,
: last beyond the command in which they are found. This also allows
: shell compound commands (like ``for'' loops) to be entered in a
: natural manner. Since this could cause problems for some makefiles
: that depend on each command being executed by a single shell, PMake
: has a -B flag (it stands for backwards-compatible) that forces each
: command to be given to a separate shell. It also does several other
: things, all of which I discourage since they are now old-fashioned.

This is a feature of parallel make. Parallel make combines all of
the commands for each target into a single shell command (if possible?).
Thus `cd's in one command affect subsequent commands. This feature
can be controlled using the undocumented .SINGLESHELL directive.
Unfortunately, the implementation of .SINGLESHELL is too primitive
for .SINGELSHELL to be worth using. Using it is equivalent to using
-B to turn off -j.
This has caused problems before. See the log message for rev.1.177
of src/Makefile for a more complicated example. (The problem for
`cd's is obvious compared with the one for `&&'s. In the example in
log message, the point of the `cd's is to maximise the damage caused
by combining non- -j-aware commands.
