--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> 2012-05-29 12:08:24 UTC --- For PR 52974 Manu made a huge improvement, so that we only get /some/ugly/path/the/user/didn't/include instead of /some/ugly/path/the/user/can't/even/parse/../../../didn't/include, but this PR suggests printing the name of a standard header instead of a physical path. This would make it harder to go and look at the relevant code, so there should be an option to display the physical path, but most users don't need to look in standard headers and can't read the uglified code anyway
