[bug #30381] Don't avoid implicit rule recursion quite so soon.

[Brent Baccala]

Follow-up Comment #15, bug #30381 (project make):

I support this feature.

I just tried to write a makefile that implicitly generates output files from
XML control files, that contain references to other files in the XML.  What I
wanted was this:


define futurebases
   $(shell xmllint --xpath "print(//futurebase/@filename)" $(1))
endef

.SECONDEXPANSION:

%.htb: %.xml $$(call futurebases, %.xml)
        $(HOFFMAN) -g $<


It doesn't work.
