what does that look like in configure.ac?

CPPFLAGS='-I/usr/local/include'

CPPFLAGS='$CPPFLAGS -I/usr/local/include'

CPPFLAGS='$(CPPFLAGS) -I/usr/local/include'

If the user specifies additional CPPFLAGS, mine should augment theirs, 
not replace them, so one of the latter two?

The first gives flags that look like this;

-I. -I.. PPFLAGS -I/usr/local/include'

the latter gives an error;

recursive variable CPPFLAGS

Apologies, but external email is thoroughly prevented, and the server 
adds the footer.
