.SECONDEXPANSION and patsubst

[Martin d'Anjou]

 Hi,

I do not understand this .SECONDEXPANSION problem with patsubst. It
seems patsubst has no effect. Here is the code:
.SECONDEXPANSION:
test_foo_core := core_bar
core_%:
        @echo CORE $@
test_%: core_$$(patsubst core_%,%,$$(test_$$*_core))
        @echo TEST $@

And how it executes:
$ make test_foo
CORE core_core_bar <<<<<< actual result core_core_bar
TEST test_foo

Expected result:
CORE core_bar <<<<<<< expected result, core_bar
TEST test_foo

I expect $(patsubst) to chop off the leading "core_" and to see
"core_bar", and not "core_core_bar".

I am sure it is something very simple, but after many hours of working
on this, another pair of eyes would be much appreciated!

Regards,
Martin
