Is this the cause or I miss something? I don't know if cgf's recent work on fifos has achieved the same extension as Linux of being able to open a fifo for read-write; but I know that Autoconf specifically avoids using <> on fifos, and instead uses a background subshell where the two forks of the shell coordinate which shell opens for read and the other opens for write, precisely because of cygwin. -- Eric Blake ebl...@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
