make does handle it (at least GNU Make, I don't know others):

If you have in Makefile.am let's say:

EXTRA_DIST = sourcefile.c sourcefile.o
test: sourcefile.c sourcefile.o
        @echo "$^"

it will work even if sourcefile.o is generated from sourcefile.c;
both will be in srcdist. Make will set things like $^ correctly
because VPATH is considered, that means `make test' tells e.g.:

address@hidden:/tmp/steffen/.../build/i386-gnulinux/test # make test
../../../../ccomm/test/sourcefile.c sourcefile.o

                                          -- cool aint??? :-)

but I would ever put generated sources to EXTRA_DIST, because in
the dist in this example file you would find:

.../test/sourcefile.c
.../test/sourcefile.o

then if you compile from that dist with builddir != srcdir and
deps enforce generation of sourcefile.o you end up with 2
sourcefile.o files: one in srcdir and other in builddir, which
(IMHO) must never ever happen.
