Further testing suggests that perhaps the only issue is the out-of-date
`configure` script. Mac OS X users with `autotools` installed should be
able to run `./boot` in the source tree to bring `configure` up-to-date,
at which point this release candidate should be buildable.

I'll cut an -rc3 with a fixed `configure` script today.

I'm having trouble setting the make file flags to make the Mac build use
the intree gmp.  I'm going to dig into this a bit more this evening.

Re: Questions on the RTS C API regarding threads and tasks

I still don't know what it is you're trying to do.  If you have a tiny
bit of optimized C code that runs quickly, then you should just make
an unsafe FFI call to it (as for as Haskell's runtime is concerned,
it's just a "fat instruction").

Anything is "callable" from C, but yes, you have to do the right
calling convention.  Primops are not easily callable from C.

An unsafe call does not detach the capability.

I don't see what the difference between this and an unsafe foreign call
is.

I still don't see why you can't just block the thread on an MVar
(removing it from the main run queues), and then when you want to
resume it write to the MVar.  It'll have an added bonus that you'll
automatically handle masking/async exceptions correctly.

If you find the MVar implementation is too slow, then maybe you
can think about making an optimized implementation which doesn't
use any synchronization / is inline in the TSO so no allocation
is necessary.  But in my opinion this is putting the cart before
the horse.

nope, my error was a bad copy and paste :)

heres a link to my build (uses the GCC style rts build, which should be
more performant than the default clang one last i checked, also has html
docs and should work OS X >= 10.7)

https://www.wellposed.com.s3.amazonaws.com/opensource/ghc/releasebuild-unofficial/ghc-7.10.2.20151105-x86_64-apple-darwin.tar.bz2
