You didn't turn the TT.alarm references into alarm in the function, so the
result doesn't compile. I'll fix it up here...

gcc at least produces really inefficient zeroing for = {} of structs. (Maybe
it's been fixed in the past couple years? I turned it into a memset anyway.)

Ok.

Speaking of which, I'm trying to cut a release in the next day or so, and long
ago you said you would put bionic and macos binaries on an android web page
somewhere? (I can build NDK binaries, but that's not quite the same build
environment as AOSP, and I haven't got a mac build environment...)

I should dig up a freebsd build while I"m at it, that defconfig hasn't seen much
attention lately either...
