           Summary: i686-linux to sh-linux cross compiler fails to compile
                    C++ files
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: dank@kegel.com
                CC: gcc-bugs@gcc.gnu.org
 GCC build triplet: i686-linux
  GCC host triplet: sh-linux
GCC target triplet: sh-linux

This is the same as bug 3774, but for SH instead of arm.
Compiling a 'hello, world' c++ program spews errors of the sort

.../g++-v3/bits/std_cstdio.h:145: `vfscanf' not declared

unless -D_ISOC9X_SOURCE is passed to the compiler.
The fix for arm appears to have been
http://gcc.gnu.org/cgi-bin/cvsweb.cgi/gcc/gcc/config/arm/linux-elf.h.diff?r1=1.31&r2=1.32
which predefines _GNU_SOURCE, with the comment
/* The GNU C++ standard library currently requires _GNU_SOURCE *

Looks like other architectures might need this, too.  I'm attaching a patch
for sh4.  No idea if it's actually right yet, but it seems logical.

> OK for 3.3 as an sh-linux specific regression fix. Thanks.
