I found a problem with sendmsg() failng when MSG_NOSIGNAL is used. It
looks like MSG_WINMASK is used in sendto() but not in sendmsg().
The patch that should fix the problem is made against
fhandler_socket.cc revision 1.176 ("should" because I did not get
around to compile the whole shebang). It clears extra flags when
calling ws2 functions in all cases of sendmsg(), recvmsg() and

Thanks for the patch. Unfortunately it's missing a ChangeLog entry and
it didn't work OOTB since it was missing curly braces, but I took the
freedom to fix it up. The change to fhandler_socket::recvfrom was not
necessary since flags is masked at the start of the function. However,
maybe it comes handy to keep the original flags value at one point, so
I removed this masking at the function start.
Please note that I can take this patch only because it's relatively
small. If you would like to send bigger patches or extensions to the
Cygwin functionality at one point, you'll have to sign a copyright
assignment form and send it to Red Hat. Please read

Other than that, patch applied with changes.
