We return -1 with errno set to EINVAL for sysconf options for values required by POSIX, but not implemented on Cygwin. This is incorrect. Return -1, but don't set errno for these options. Drop the "nsup" enum to indicate unsupported values, it's not required anymore. Fixes: 59e3b6ca7dc10 (CVS import) Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
