Problem about multiple targets

[董理]

Dear all,

I want to write a rule with multiple targets as following:

        ${TARGET}: $(addsuffix .F90, $@) ${OBJECT}
                ...

Every target "<TARGET>" has a corresponding source file "<TARGET>.F90",
so it is different from the example in Info pages of make. But the
automatic variable "$@" has no value in the prerequisite. How to solve
this problem?

Thanks for help!
