Looking at the surface, it appears as if not very much is currently

that allows you to access the GHC developers' mailing list, and
woooooo-boy, it looks pretty damned busy in there! o_O
There's nothing closed about the GHC developer list - feel free to
join, or just read it from the archives or GMane.
I feel my IQ is far too low for that. ;-) [Not to mention that the
traffic volume looks insane...]
On the subject of DLLs, there's an important distinction to make.
1. putting the whole program/library in a DLL that you can call from C
2. putting individual Haskell packages in DLLs that you can call from
Haskell.
(1) has always been supported (temporary breakage notwithstanding) and
as far as I know will work in 6.10.1. (2) was supported a long time
ago for a short while, and we'd like to bring it back, but as part of
a multi-platform effort to support shared libraries.
To get (1) you just do ghc -shared, I believe (I'm not by a Windows
machine right now so can't check).
(1) is not of huge interest to me, but it's pleasing to know that it's
possible. (I don't actually know how DLLs work, but presumably if I were
to dig around in System.Win32 I could also call normal DLLs from Haskell
too if I desire...?)
(2) is something I'd like to see - and I aplaud you for seeking to make
this a portable thing! (As well it should be.) One or other of the
developer wiki pages lists this as "things we'll definitely do for
6.10"; can you confirm or refute that?
Also, I read somewhere that you are/were looking at making the RTS into
a DLL. What's the status with that?
Given that I know virtually nothing about how such low-level things
work, and I have no clue how GHC works internally, is there anything
useful I can do to help you guys with this stuff? I mean, other than
complaining that it's not done yet... ;-)
