7.8 Release Update

[Kazu Yamamoto ( 山本和彦 )]

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?
