object `foo.$(OBJEXT)' created both with libtool and without

[Harlan Stenn]

Automake-1.6.3.

So I have a Makefile.am that build both PROGRAMS and LTLIBRARIES.

One of the .c modules is used by both a program and a library.

I get the warning:

 automake: foo/Makefile:NN: object `foo.$(OBJEXT)' created both with libtool
  and without

and I'm assuming it's because this case is not being caught by the same code
that handles:

 bin_PROGRAMS = ctags etags

 ctags_SOURCES = etags.c
 ctags_CFLAGS = -DCTAGS

 etags_SOURCES = etags.c
 etags_CFLAGS = -DETAGS

or maybe it would if I had target-specific CFLAGS (which I don't, at
present).

Suggestions on how I can remedy this problem?
