[PATCH v2 1/6] mingw: correct exit-code for SIGALRM's SIG_DFL
From: Erik Faye-Lund <hidden>

Make sure SIG_DFL for SIGALRM exits with 128 + SIGALRM so other processes can diagnose why it exits. While we're at it, make sure we only write to stderr if it's a terminal, and change the output to match that of Linux.
