Hello world,
the attached patch fixes the regression by making sure we never
try to create a temporary variable from a temporary variable,
which happened in the wrong order.
Regression-tested. OK for trunk and 4.9?

This bug is caused by my last patch, which did not differentiate
between explicit section names (via attributes) and implicit section

This patch fixes that.

Backport from trunk (r212694) failed to fixup gcov_read_counter
invocations in google-specific code. Also, forward port

fixup.
Passes manual testing, ok if passes regression tests?

Hi,
a few cases where under SFINAE we just go ahead and we don't immediately
return error_mark_node. During the work I also noticed a glitch in
cxx_sizeof_or_alignof_type where we do complain tf_warning_or_error
but in that case complain is a bool.
Tested x86_64-linux as usual.
Thanks,

Trunk no longer set SECTION_NAME for implicit section names, so this
probably does not apply to trunk. It's probably not necessary for
trunk either.

This patch implements __cxa_atexit support for Cygwin targets. This
requires Cygwin 1.7.32 and binutils master.
Net difference in check-c++ results on i686-pc-cygwin:

# of unexpected successes -3
# of expected failures -61

Thank you. I fixed the typo and committed.

The attached patch implements premature DLL unloading prevention in
__cxa_thread_atexit for Cygwin and MinGW-w64 targets. The mingw.org
target is welcome to do the same in their os_defines.h, but this code
does require Windows XP/2003, and they have historically catered to
older platforms.
