Details:
I was trying out the example in the "Secondary Expansion" part of the manual,
and the expansion of $$< seems to be wrong in both 3.81 and CVS. For example,
this Makefile:
.SECONDEXPANSION:
foo: bar q$$<
%:
@echo This is the general rule for $@ with deps $^
Gives this output:
$ make foo
This is the general rule for bar with deps
This is the general rule for qfoo with deps
This is the general rule for foo with deps bar qfoo
i.e. $$< appears to have been expanded to "foo", whereas I would expect it to
be expanded to the empty string.
