            Bug ID: 57653
           Summary: filename information discarded when using -imacros
           Product: gcc
           Version: 4.8.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: allan at archlinux dot org

When compiling with the "-imacros" flag, the file name information is lost in
error messages and backtraces.

e.g.

> gcc-4.8 -imacros i.h test.c 
<command-line>: In function ‘main’:
<command-line>:5:1: error: expected ‘;’ before ‘}’ token

Since Jakub posted a patch for the PATH problem [1] and it seems that the
permission issue might be a non-issue [2] is there anything else let for this
bug?
