             Bug #: 50048
           Summary: "cc1: note: obsolete option -I- used, please use
                    -iquote instead" during bootstrap
    Classification: Unclassified
           Product: gcc
           Version: 4.6.1
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: ada
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ludovic@ludovic-brenta.org
              Host: i386-linux-gnu
            Target: i386-linux-gnu
             Build: i386-linux-gnu


During bootstrapping with ada enabled, I get this message multiple times:

cc1: note: obsolete option -I- used, please use -iquote instead

because of line 250 in gcc/ada/gcc-interface/Makefile.in.

Recent changes in the glibc header files have caused GCC to fail to bootstrap
on i386; see http://bugs.debian.org/637418.  Replacing -I- with -iquote as
suggested fixes this.

This is still a problem for 4.8.0.  Offending lines are around line 270:


# Specify the directories to be searched for header files.
# Both . and srcdir are used, in that order,
# so that tm.h and config.h will be found in the compilation
# subdirectory rather than in the source directory.
INCLUDES = -I- -I. -I.. -I$(srcdir)/ada -I$(srcdir) -I$(srcdir)/../include

ADA_INCLUDES = -I- -I. -I$(srcdir)/ada
