[PATCH 0/2] SIGPIPE masking in local socket connections, v2

A new approach to avioding manipulating the signal mask during for every
send - this time round, use SO_NOSIGPIPE and MSG_NOSIGNAL if available.

The patches have been tested on Linux and OSX, and I've confirmed that
'struct foo { };' will compile with a MSVC compiler. I'd still like a
little more testing though, is there a machine that allows both
SO_NOSIGPIPE and MSG_NOSIGNAL?

Again, comments most welcome,

Jeremy
