Last night I realized we could solve this by introducing a new
variable in Makefile.in to represent each patsubst expansion. Such a
variable would be given the same conditions as what it depended on and
would be expanded by automake. The `derived' variable would be
rewritten to refer to this new variable. I think that solves all our
problems and is fairly easy to implement.
Well, it is easy if you do patsubst expansion in a separate pass, to
handle cases like this:
if FOO
var = a b
endif
derived = $(var:%=%.c)
if BAR
var = c d
endif
