           Summary: [4.6 regression] missing error message for -I
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: ebotca...@gcc.gnu.org


The error message for a missing argument to -I has disappeared.  It used to be:

gcc: argument to '-I' is missing

Now a cryptic message is issued:

cc1: fatal error:
/home/eric/build/gcc/native32/gcc/../lib/gcc/i586-suse-linux/4.6.0/: No such
file or directory
compilation terminated.

As a matter of fact, the Ada compiler is also affected.
