haskell - How do you install GHC into Cygwin or point Cygwin to GHC? -

i attempted point cygwin installer http://haskell.org/ghc/cygwin, installer unable find setup.ini.sig. if possible, how alternatively edit .bashrc reference installation made using setup binaries in c:/ghc/.

when installed windows version of ghc, added binaries location path environment variable, able run cygwin's bash fine. i've never attempted install or compile ghc on cygwin itself.
