The attached demonstration program blocks signals (with sigprocmask())

receipt of a
blocked signal. On "CYGWIN_NT-10.0 2.7.0(0.306/5/3) 2017-02-12 13:18
signals regularly arrive despite being blocked. Essential parts of
program include handling two signal numbers and having handlers run
least 1-2ms; this problem goes away if I remove one of those
GNU/Linux, AIX, Solaris, and "CYGWIN_NT-6.0 1.7.27(0.271/5/3)

behavior is non-conforming.
I do not think that Cygwin is the problem here; your code is the
here, I believe.
You cannot use SIG_SETMASK in that context.
You cannot use SIG_SETMASK in that context in the way you do.
