OK, but this isn't very clear, as the description under -isystem says "*all* directories specified by -I". I'd replace "all" by "non-ignored". The behavior w.r.t symbolic links to such directories should also be specified. Now, this behavior, if it is intentional, leads to 2 questions: 1. Shouldn't -L have a similar behavior to ensure consistency between library search paths and include search paths? 2. Software is often compiled with configure, make, make install. How can one force the compiler to look in /usr/include & /usr/lib first (i.e. override the user's environment)? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31186
