Fix 27_io/filebuf_members.cc
* src/localename.cc (locale::_Impl::_Impl(const _Impl& __imp,
const string& __name, category __cat, size_t __refs): Set
_M_has_name with _M_name.
* include/bits/localefwd.h (locale::operator!=): Protect member
function call with this->.
* src/locale.cc (locale::operator==): Make fast checks first.
* include/bits/basic_ios.tcc (basic_ios::init): Simplify.
* include/bits/ios_base.h (_M_synced_with_stdio): Add data member
to ios_base::Init.
* src/ios.cc (ios_base::Init::Init): Initialize here.

* config/c_io_stdio.cc (__basic_file<_CharT>::sys_open()): On
systems that support it, call dup() before fdopen().
From-SVN: r38742
* cpplib.h (struct cpp_reader): Add help_only field.
* cppinit.c (COMMAND_LINE_OPTIONS): Add OPT_version.
(cpp_handle_option): Set pfile->help_only if we see -h,
--help, -target-help, or --version. Print version string but
do not set help_only if we see -v or -version. Make text
printed by -v match that printed by (-)-version.
* cppmain.c (main): Exit after option parsing if
pfile->help_only is true.
* toplev.c (independent_decode_option): Call print_version,
then exit, if we see --version (but not -version).
(print_version): Split lengthy message into two lines.
From-SVN: r38733
* function.c (reorder_blocks): Make sure the flags are all reset
before using them to mark blocks, else a second invocation will
corrupt the block chain.
(reorder_blocks_0): New, resets the flags.

* varasm.c (mark_constant_pool): Improve initial comments.

* config/avr/avr.c (avr_peep2_scratch_safe): New function.
* config/avr/avr.md (all peepholes that request a scratch register):
Call it, FAIL the peephole if not safe (in interrupt functions).

array futures. Abort if we try to initialize an array of
unspecified length with a non-empty constructor in the middle
of a structure.
