Just a heads up that cygwin 1.5.6 is released and has much better
SystemV IPC, though the cygserver that actually does the work wasn't
included AFAICT; and even if it was included, installing it as a service
is an extra manual step that may or may not be performed.

I'm going to work on a patch to skip the failing IPC::SysV tests if
the server isn't actually running (AIUI the system calls will give
SIGSYS in this case), and also to set d_semctl_semun and maybe
d_semctl_semid_ds in cygwin hints (since the configure test will fail
if the ipc server isn't running).

Also, I'm going to remove the IPC::SysV hint that was using the now
deprecated cygipc library.  (AIUI, we didn't actually support using
cygipc as it wasn't good enough, or so Jarkko's comment in the main
hints/cygwin.sh has me thinking.)  If anyone sees a need for
supporting a choice between cygipc or cygserver, scream now.

Any other comments also appreciated.
