>Description:

	PMake doesn't seem to notice implicit dependencies for single
	suffix rules.  Other makes (eg. GNU Make 3.76.1) do.

>How-To-Repeat:

	The following example fails to build anything with make, but
	works as expected with gmake:

cat <<'END_OF_FILE' > Makefile
.SUFFIXES: .sh

.sh:
	@rm -f $@
	cat $@.sh > $@
	chmod +x $@

all: foo bar

foo bar: Makefile

END_OF_FILE

touch foo.sh bar.sh
rm foo bar
make

	The work-around is to add explicit dependencies for the .sh
	files:

cat <<'END_OF_FILE' > Makefile
.SUFFIXES: .sh

.sh:
	@rm -f $@
	cat $@.sh > $@
	chmod +x $@

all: foo bar

foo bar: Makefile

foo: foo.sh
bar: bar.sh

END_OF_FILE

touch foo.sh bar.sh
rm foo bar
make


>Fix:

	Unknown.
