Hi,

When porting goredo to OpenBSD I noticed that while the software
compiles without any issue, it does not run as expected. Specifically,
it consistenly errored out before doing any actual work with a "function
not implemented" error message. Happens with latest release (2.6.2) and
latest git master.

It is a known issue with software that uses old versions of
'golang.org/x/sys' module. It seems like at some point OpenBSD devs
changed some macro values in libc and it irreversibly broke old versions
of the aforementioned module that expected different macro values.

The only fix I know of is to update the module in question. Diff against
git master below.

By the way, could a maintenance release be made (based on 2.6.2) with
this fix? This would allow me to drop patches from the OpenBSD port.
Even if not, thanks for your attention.
