Comment:

 I have a patch that improves the windows implementation of
 `getExecutablePath` so that it follows symlinks at
 https://phabricator.haskell.org/D4227 -- feedback welcome.

 This however does not change ghc, ghc-pkg and hsc2hs to use
 `getExecutablePath` (instead of the current duplicated code that does
 something equivalent).
