+build !cgocheck

[mattn]

go1.6 doesn't allow passing Go's pointer into C. And it seems to be possible to disable pragma +build !cgocheck.

I try to add this into go-gtk. But the error always displayed.

Enyone know who to disable this feature? I can disable this with set $GODEBUG=cgocheck=0.

No, using a cgocheck build tag was an idea I tried out but it was
never committed to the tree.

That is what you have to do to disable the check.

Of course, the code should eventually be changed.

Yes, I understand. But probably, I might not be possible to fix all about this until release of go1.6 .
