Is there any way to warn about /usr/include without warning about
/usr/local/include?  Packages that add -I/usr/include are buggy and the
maintainers need to fix them, whether they realize that or are willing to
face it or not.  I have no sympathy there.  But -I/usr/local/include is
less obviously wrong.
