# HACK: On Windows, symlinks have two different types: file and directory,
#       if the target path doesn't exist when the symlink is created,
#       Cygwin will fallback to create a non-native link, which makes the
#       symlink unusable to pure Win32 apps (e.g. our compilers) later.
#
#       Since the target path may not exist at the time of creation, we can fix
#       this by deleting all the symlinks after the first checkout and
#       letting Git to re-create them for us.
