What I want is this:

In configure.in, call

AC_REPLACE_FUNCS([inet_aton ...]) # the whole list

If you need more sophisticated checks on top of "function exists", you
keep the existing tests, but instead of, say,

SNPRINTF=snprintf.c
AC_SUBST(SNPRINTF)

you'd call

AC_LIBOBJ(snprintf)

In Makefile.global.in:

LIBOBJS = @LIBOBJS@

In utils/port/Makefile:

libpgport.a: $(LIBOBJS)
ar crs $@ $^

In Makefile.global.in:

Add -L$(top_builddir)/src/port to LDFLAGS (near the start), -lpgport to
LIBS (near the end).

Then you need to make sure that the src/port directory is build before
being referred to.

In the libpq makefile, you can write the rules like:

ifneq(,$(filter snprintf.o, $(LIBOBJS)))
# do what it's doing now in case of 'ifdef SNPRINF'
endif

Caveat implementor.
