Comment(by royliu@…):

 Doesn't setting `p->add_sysroot` back to false imply the default behavior?
 From your bug report, I got the impression that you wanted the MacPorts
 `gcc-apple-4.2` to search in an Xcode SDK.  Unless I am mistaken, the only
 way to make this happen is to replace `/opt/local/include` with
 `/user/include`.
