Generate a warning if the return value of FilePath::Append is ignored. There's currently a GCC bug which stops this working for return values which have a destructor. Hopefully this will help someone in the future, with future versions of GCC. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38172 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31742 Review URL: http://codereview.chromium.org/11494 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@5871 0039d316-1c4b-4281-b951-d872f2087c98
