   AC_PROG_LIBTOOL calls AC_PROG_CC which sets default CFLAGS
   (but only if they are not already set).

so what is the recommended way to get configure-generated flags
into AM_CFLAGS, leaving CFLAGS empty?  i see in many places:

 [...] $(AM_CFLAGS) $(CFLAGS)

and would like CFLAGS to be settable by the user w/o requiring
them to "merge" their values w/ the existing ones.  that's what
AM_CFLAGS is for, it seems, but i see AM_CFLAGS always empty.


AM_CFLAGS is reserved for developers. It's not a problem if the user overrides the default value of CFLAGS since CFLAGS is reserved for the user.
