I've seen the same behavior with mingw but never bothered tracking it
down.. I worked on that portion of the code in 2005 to get the ctrl-c
behavior working correctly. However, the most competent person in that
section of the code is probably Paul Kienzle as he proposed the solution
for the original signal handler for mingw.
