The approach I had been thinking about shouldn't depend on the
automake version involved. One option would be to just put a pattern
override rule for each g-wrap file in the relevant Makefile.am's.
GW_CFLAGS := $(filter-out -Wno-uninitialized, $(CFLAGS) $(CPPFLAGS))
gw-foo.c gw-foo.h: gw-foo-spec.scm
gw-foo.o: gw-foo.c gw:foo.h
$(CC) -c ${GW_CFLAGS}
Of course if you're not willing to presume GNU make, this won't work,
but there are plenty of other variations on this theme that could
probably be designed to work just fine. Heck, if you wanted to run a
script or similar at the end of configure.in, and use make "includes"
then you could possibly even automate most of the process with or
without GNU make.

I'm also concerned about things like alignment on various archs,
though I agree that we can almost certainly come up with something,
even it it requires some #ifdefery that should work.
