not really :) e.g. my output on a Windows Vista system with GHC 6.10.1
cabal install sdl

Configuring SDL-0.5.4...
setup.exe: sh: runGenProcess: does not exist (No such file or directory)
cabal: Error: some packages failed to install:
SDL-0.5.4 failed during the configure step. The exception was:
exit: ExitFailure 1
To build this I guess I would have to install MinGW and MSYS (which is already insanely hard to unzip all the latest development stuff in the right places and configure it correctly, especially for a windows user), and then do all kinds of tricky things that are obvious for unix people but alien for dummy windows users like me :)
Anyway, support for Windows users gets better each year, which is great!
