commit fcec4830abf0aa4821ba1a5dd1d9fb35d671cb85 Author: Corinna Vinschen <[email protected]> Date: Wed Mar 2 22:02:24 2022 +0100 Cygwin: sysconf: don't set errno for unsupported options 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.
