One of these is that ghc be in a folder named `bin` and that `../lib` exists. This pattern doesn't hold for symlinks as a link `C:\ghc-bin\` pointing to `C:\ghc\ghc-7.10.3\bin` will break this assumption. This patch resolves symlinks by finding where they point to and uses that location as the base for GHC. This uses an API that's been introduced in Vista. For older systems it falls back to the current behavior of not resolving symlinks. Test Plan: 1) Create symlink to GHC's bin folder. 2) Run GHC from that folder.
