Subject: Restoring use of socketpair on cygwin.
X-Git-Tag: v3.1.1pre1~14
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9e2e7a1b2d921a56cbf8f8a76d6fdc12af8d07f8;p=thirdparty%2Frsync.git

Restoring use of socketpair on cygwin.

Use of socketpair is much faster on cygwin, and some folks report fewer
hangs using the modern socketpair implementation vs pipes.
