Problems with ansi2knr

Hi all; I'm using automake 1.7 (with autoconf 2.54 and gettext 0.11.5).
I'm trying to add ansi2knr support so I can use ANSI function
definitions in GNU make.

I have special code to test the getloadavg.c, which builds a test
program using that code.  The test program is embedded in the file, and
enabled with a -DTEST to get a main(), etc.  I have this in my

  AUTOMAKE_OPTIONS = 1.7 dist-bzip2 check-news ansi2knr


  # The loadavg function is invoked during "make check" to test getloadavg.
  noinst_PROGRAMS = loadavg
  nodist_loadavg_SOURCES = loadavg.c
  loadavg_CFLAGS = -DTEST

  loadavg.c: $(srcdir)/getloadavg.c
          cp $(srcdir)/getloadavg.c loadavg.c

This works for normal builds, but fails during builds without ANSI

The problem is that when the rules to build loadavg-loadavg.o are
created, they depend on just loadavg.c, instead of loadavg$U.c.

For example:

  loadavg-loadavg$U.$(OBJEXT): loadavg.c
  loadavg-loadavg$U.o: loadavg.c
  #       if $(CC) $(DEFS) ...
          source='loadavg.c' object='loadavg-loadavg$U.o' libtool=no \

I have a rule that constructs a loadavg_.c from loadavg.c:

   loadavg_.c: loadavg.c $(ANSI2KNR)
           $(CPP) $(DEFS) $(DEFAULT_INCLUDES) [...]

but it's never being invoked because the ...$U.o depends on the plain
....c instead of the ...$U.c.
