On Cygwin 2.8.1 x86_64, I've found that g++ std:map initializing

The binary compiled with cygwin-devel-2.8.0-1
does not raise segmentation fault
even if on Cygwin 2.8.1 x86_64 environments.

Here's sample code for reproduce.
I've just checked that the problem occurs with the 2017-06-20 snapshot
but not with the 2017-06-06 snapshot.
I did the bisection:

Feature test macros overhaul: Cygwin signal.h
This should match newlib's <sys/signal.h>.
Ken, thank you for bisecting this. I'm testing a fix now.
