+dnl Add an include-directory to $CPPFLAGS. Don't add /usr/include, since it's
+dnl redundant. We don't normally need to add -I/usr/local/include for gcc,
+dnl but old versions (and some misinstalled ones) need that. To make things
+dnl worse, gcc 3.x may give error messages if -I/usr/local/include is added to
+dnl the include-path).
