Thanks for noticing this!

What I intended is that by default everything is compiled with
AM_CFLAGS.  But if there are per-executable CFLAGS in effect, then
AM_CFLAGS is omitted.  So I agree you've found a bug.

Your message, plus my recent adventures into automake.texi, make me
wonder if this is the best approach.  It would certainly be easier to
document if AM_CFLAGS was simply always used.

Now is the time to decide this sort of thing -- before 1.5 goes out.
Any comments?  Reasons to prefer one over the other?  As I recall I
planned it this way on the theory that adding AM_CFLAGS to the per-exe
CFLAGS is easy for the user, but removing it would be hard.
