Good question.  Actually, unless you know of a definite header that's
present in /usr/local/include, I wouldn't know how to find this out
portably.  Why not add it by default, or even better, just let the user
add it:
  ./configure CPPFLAGS=-I/usr/local/include

if it is needed on her system?

CFLAGS wouldn't be right, because -I is a preprocessor variable.

Well if you need the flag at configure time, add it to CPPFLAGS, either
by the user as above, or by you in configure.ac.  But I would reserve
this to the user; she might have a broken version of the headers you're
looking for there.

Such message footers are frowned upon on public lists, and easily
avoided by using non-work email accounts if need be.
