Would it be possible to warn explicitly about -I inclusion of directories
that have fixincluded headers? I think a message such as
cpp0: warning: directly searching directory /usr/include, which has
fixincluded headers
would be clearer to people.
Or, alternately, could the preprocessor just automatically translate
-I/usr/include into -IPREFIX/whatever/include -I/usr/include?
