lib/settings file wrong

This is what ghc-7.2.2/lib/settings looks like on my machine after normal installation with the Windows installer:

[("GCC extra via C opts", " -fwrapv"),
 ("C compiler command", "$topdir/../mingw/bin/gcc.exe"),
 ("C compiler flags", ""),
 ("ar command", "D:/slave/stable/builder/tempbuild/build/inplace/mingw/bin/ar.exe"),
 ("ar flags", "q"),
 ("ar supports at file", "YES"),
 ("touch command", "$topdir/touchy.exe"),
 ("dllwrap command", "$topdir/../mingw/bin/dllwrap.exe"),
 ("windres command", "$topdir/../mingw/bin/windres.exe"),
 ("perl command", "$topdir/../perl/perl.exe")]

It seems that ar command is completely wrong.
