[holmes000]

There was an attempted fix in #1769 but the PR got closed. Those errors come from U await_resume() KJ_NOINLINE, apparently moving KJ_NOINLINE to the beginning of the line fixes them - KJ_NOINLINE U await_resume().

It is fixed in v2 - #1732.

[kentonv]

I think this is fixed by #1819 but I haven't gotten around to doing that 1.0.2 release. :/

If someone can confirm (hard for me since I don't have a Windows box), then I'll get on that release...

[holmes000]

I can confirm that commit 990f469 fixes the problem, but I haven't tested the PR as a whole.

[kentonv]

I finally managed to release 1.0.2, sorry for the delay.
