Details:

Makefile allows to create pattern rule with multiple targets, like below. This
is very handy for rules which generates multiple files at once.


%.h %.c : %.idl
        touch $(<:%.idl=%.c) $(<:%.idl=%.h)

I tried to build static pattern rule in similar way, but it do not work - make
reports error "multiple target patterns":


$(IDLS:%.idl=%.c) $(IDLS:%.idl=%.h) : %.h %.c : %.idl
        touch $(<:%.idl=%.c) $(<:%.idl=%.h)

I tested this using make 4.0 on Linux. Please fix this.
