I think someone is confused (me or you). -m/--max-timeout is for
total transfer time and -c/--connect-timeout is for name resolution only AFAICS.
If '-c', yes libcurl could fork off gethostbyname() in a separate thread and
call WaitForSingleObject (.., timeout) on the thread handle. I did just this
for Wget; look at function run_with_timeout() in mswindows.c.

The '-m' option could be done by emulating SIGALRM using 'timeSetEvent()'
from winmm.lib (gettimeofday() already uses that if WITHOUT_MM_LIB
isn't defined). But alarmfunc() cannot longjmp out of the event-callback.

I'm not sure how siglongjmp() is different from longjmp() in this respect,
but I wonder how this is safe to do in any environment. Not to mention
it's not thread-safe to have only a single jmpbuf.
