--- Comment #5 from Sylpheed <typesylph at gmail dot com> ---
Please try these patches for trunk(4.9.0).

1. gcc/gcc.c
line 2548
<       if (sysroot_len > 0
---
>       if (sysroot_len > 1 

2. gcc/incpath.c
line 182
<           if (sysroot_len > 0 && sysroot[sysroot_len - 1] == DIR_SEPARATOR)
---
> 	      if (sysroot_len > 1 && sysroot[sysroot_len - 1] == DIR_SEPARATOR)

There patch is for 'host-compiling' with '--withsysroot=/'.
Anyother promrems defferent env('cross-compiling') the other problem may be.

            Bug ID: 57926
           Summary: Atomic functions broken with C++ but not C?
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: lailavrazda1979 at gmail dot com

Note that this possible bug does not trigger with GCC, only G++.

Try compiling the code in the attachment with g++. It'll give strange errors,
including complaining that an argument must be a non-void pointer when it IS in
fact, a non-void pointer.
