Static pattern rules with more than one '%'

[Alejandro Colomar]

Hi!

<https://www.gnu.org/software/make/manual/html_node/Static-Usage.html>

The documentation of static pattern rules says that each pattern *normally*
contains the character '%' just once.  That wording seems to allow the case
of several of those.  I experimented to see if it is really supported, and
what the semantics are, since the documentation doesn't really say how such
a thing would behave.  It seems it doesn't really work, though.

$ cat Makefile 
.PHONY: all
all: foo.3.bar

%:; echo $@

foo.3.bar: %.3.%: %.5.%; echo $@
$ make
Makefile:6: target 'foo.3.bar' doesn't match the target pattern
echo foo.3.bar
foo.3.bar


Am I missing something?  Is something like that allowed anyhow?

Cheers,
Alex
