[ruby-dev:18047] msvcrt

  Hirofumi Watanabe posted a plan to unify mswin32-ruby and mingw32-ruby.
  The name of both DLL became `msvcrt-rubyXX.dll', and default site-install
  directory of extensions became "i386-msvcrt". So, ruby's library search
  path is as follows:

    % msvcrt-ruby17 -e 'puts $:'
    d:/ruby/lib/ruby/site_ruby/1.7
    d:/ruby/lib/ruby/site_ruby/1.7/i386-msvcrt
    d:/ruby/lib/ruby/site_ruby
    d:/ruby/lib/ruby/1.7
    d:/ruby/lib/ruby/1.7/i386-mingw32

  These changes have already been applied to latest ruby-1.7.
