Bug filed: https://bugs.swift.org/browse/SR-2309
I've prototyped potential solution #2 this morning (embedding yet another
copy of the blocks runtime into libdispatch). I need to do a little
cleanup of the build plumbing, but it is workable.
I have time to work on it this week once there is a consensus on the
approach.

Can someone file a bug to track how we are going to resolve this issue, and
outline our options? I want to make sure we have enough eyes on it to make
sure we get what we need for Swift 3.

I had a quick conversation with Daniel Dunbar on this. Adding -Xcc
-fblocks as a default option to Swift PM (on Linux). The wrinkle is
the availability of the blocks runtime - it would either need to
become a pre-req for Swift, or needs one to be built into the
package.

Hi Tony,
Hopefully this is on the task list already, but if it isn't we should
add it before it gets to be too late to change the compiler...
When compiling a Swift program on Linux that imports Dispatch (or
Foundation once the integration is done), the user has to give the
extra compilation flags -Xcc -fblocks to enable block support.
We really need to land a change somewhere so that either (1) blocks
support is always on for Linux or (2) importing Dispatch or
Foundation automatically turns on blocks support.
I have some time today and tomorrow that I could use to work on this
if no one is handling it already, but I'm not sure how best to tackle
the problem. Suggestions?
