I think this is *awesome*.  I would really like to see this included in 
autoconf.  It helps developers (by automatically warning them of problems) and 
later builders (many build warnings are a warning signal that the code *may* be 
of poor quality).

I note that this also includes "AC_APPEND_FLAG", which is a great 
general-purpose mechanism for portably setting compiler flags (it only sets 
flags if the compiler supports the flag).
