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

I attempted to point the C开发者_如何学Goygwin installer to http://haskell.org/ghc/cygwin, but the installer was unable to find setup.ini.sig. If possible, how could I alternatively edit my .bashrc to reference an installation made using the setup binaries in C:/ghc/.

When I installed the Windows version of GHC, added its binaries location to my PATH environment variable, I was able to run it from Cygwin's BASH just fine. I've never attempted to install or compile GHC on Cygwin itself.

Just add --no-verify to setup.exe which means

Don't verify setup.ini signatures
