[Haskell-cafe] linking warnings when using regex-posix package in GHCi 7.8.1 RC2

[Rouan van Dalen]

Hi Cafe,

I have the following program:

=========================

module Main where

   import Text.Regex.Posix

   main = do
      putStrLn "!!!"

=========================

When I run the main function from within GHCi, I get the following output from GHCi:

=========================

=========================


Does anyone have an idea why GHCi is even linking against msvcrt?
And is there a way to fix this?

I am using GHC 7.8.1 RC2 x64 on Windows 8 x64
