I re-compiled and ran the test program under Cygwin 1.7.17 as well as on several Linux machines (Debian/Fedora/Gentoo/Ubuntu, kernel versions 2.6.29/2.6.32/3.0.6/3.2.0/3.2.12/3.4.9/3.6.6, different kinds of CPUs etc.) and I definitely see a difference. The difference is that after typing in the commands kill -SIGUSR2 [pid] kill -SIGUSR1 [pid] kill -SIGUSR2 [pid] kill -SIGUSR1 [pid] (in this order!) in another console, the program blocks under Cygwin while it exits normally under Linux. The last output under Cygwin is 'thread 2 waiting for SIGUSR2' while under Linux, one more line 'thread 2 received SIGUSR2' is printed out before the program exits.
