Please always reply to the mailing list rather than to me directly, that
way others can help you if I'm unavailable and the answers are available
in the archives if other people are searching.

Anyway, the only way to do what you want is to declare four different
rules.  I don't know why you're using static pattern rules here instead
of regular pattern rules, but I think you need to rewrite your example
above to be this:

$(wdir)/%.o: %.f
        $(COMPILE.f) $< -o $@
$(wdir)/%.o: %.F
        $(COMPILE.f) $< -o $@
$(wdir)/%.o: %.f77
        $(COMPILE.f) $< -o $@
$(wdir)/%.o: %.f90
        $(COMPILE.f) $< -o $@
