Cygwin supplies a posix layer for windows and so no mingw doesn't have 
these. Some things are in libg32w from the gnuwin project, but a lot are 
stubs. The code to handle ctrl-c in octave under mingw forks a new 
process suspends the old ones, changes the old processes context 
restarts the old thread and then kills the new thread. This is due to 
the fact that under windows you can't change the context of a running 
thread. In any case this means that there are examples of how to 
implement this under Windows in a basic way. However, I believe 
CreateProcess will copy more of the current process information than a 
posix fork, so will be more expensive.

If I remember correctly, I think there is a windows call closely 
resembling socket and so this one shouldn't cause problems to create.
