lib/settings file wrong

[rl]

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.

Thanks for the report. Fixed by:

    Define "ar command" correctly in settings file on Windows
    
    We want to use the inplace ar, rather than whichever ar the
    machine that we build on happens to have.

You can fix your 7.2.2 installation by editing c:/ghc/ghc-7.2.2/lib/settings and changing the ar command entry to:

 ("ar command", "$topdir/../mingw/bin/ar.exe"),
