Kazu,
Dynamic should be available with anything, including profiling. This
is probably more an artifact of your mk/build.mk setup.
When you look in there, check carefully which BuildFlavour you have
set. The relevant variable is GhcLibWays. For example,
BuildFlavour=perf will add 'p' which is profiling, and also 'dyn' if
the platform supports shared libraries. BuildFlavour=quick however,
would not set this.
If you have a build tree, you can do:
$ make show VALUE=GhcLibWays
which should print out a string containing the enabled Ways.

Hi Austin,
I would like to ask about profiling and dynamic linking.
If I understand correctly, GHC 7.8 with cabal-install 1.18.x.x uses dynamic linking by default (except on FreeBSD). But GHC 7.8 provides a profile library only for static linking. An example is the base library:
libHSbase-4.7.0.0.a libHSbase-4.7.0.0-ghc7.7.20130907.so* libHSbase-4.7.0.0_p.a
Profile libraries for dynamic linking are not provided. So, I got troubles when I tried to take profile of my programs. I need to specify "--disable-shared" explicitly to cabal-install. (This sometime fails if Build-Type: is Custom.)
Is this intentional? Are there any technical reasons to not provide dynamic profile libraries?

Friends,
After talking with SPJ, we've decided that the cutoff date for the 7.8 feature window will essentially start on Monday, the 16th. This is the beginning of the week before ICFP. This is a week from tomorrow.
Afterwords, I suspect we will cut the 7.8 branch in early October (my notes tentatively say Oct. 9th.) This will give us a few weeks of straight bugfixing.
Don't let this scare you too much. We're doing this at the beginning of the week so we have time to sort things out. Bug fixes will of course continuously be welcome until the 7.8 branch.
However, for pending features, I'd like a status update. Everyone mentioned below, please reply to clarify anything:
* Iavor Diatchki and SPJ are working together on the type-nats-simple branch. I believe this will hopefully land in time. Iavor, SPJ - can you comment here?
* Trevor and Iavor are also working on kinds without data. Any word here?
* Geoffrey is currently moving, but he says the SIMD work and new template-haskell work will land by the end of this week, which is great.
* Patrick Palka has a few loose ends to tie off for the parallel compilation driver. I talked to him today, and after Andreas committed his bugfix to base, I believe everything is now working, with the deadlocks sorted out. Patrick, can you confirm? We can get this merged ASAP if so.
* Pedro and Richard - what's the story on propositional equality, etc? This is mentioned on the status page[1] but I'm not sure what else needs to be done. I know Pedro committed the work to make manual Typeable instances an error, which is great.
* Luite and Edsko will be talking about some final changes to the hooks patch, and afterwords it can hopefully be integrated. I'll keep up with them this week.
* I am currently working on integrating the Applicative-Monad warning, but this requires some upstream patches for the build to work. However, we still need to sync several upstream libraries, and this will be happening over the next few weeks. Therefore, I may commit it, and incrementally fix validation errors as time goes on and me and Herbert sync upstreams.
IMO, most of these look to be in good shape, I think.
If you *do not think you'll make it by the 16th*, please let me know. We can possibly still land it the week of the 16th, provided I know ASAP. But we really really need to know, because many people will be gone the following week.
In the following few days, I'm hoping going to finish off everything I can in the patch queue, and fix my remaining bugs, and investigate Dynamic GHCi in particular.
Again, if you don't think you can make it on the 16th, but still within the week, we can of discuss it.
