Interesting, that didn't happen with ruby_1_8_6 or trunk.

          CROSS_COMPILING = RUBY_PLATFORM; \
          remove_const :RUBY_PLATFORM; \

But ruby_1_8 branch is different: (i386-mingw32-fake.rb)

class Object
  CROSS_COMPILING = RUBY_PLATFORM
  remove_const :RUBY_PLATFORM
  remove_const :RUBY_VERSION
  remove_const :RUBY_DESCRIPTION if defined?(RUBY_DESCRIPTION)
  RUBY_PLATFORM = "i386-mingw32"
  RUBY_VERSION = "1.8.8"
  RUBY_DESCRIPTION = "ruby #{RUBY_VERSION}
(#{Time.now.strftime("%Y-%m-%d")}) [#{RUBY_PLATFORM}]"
end
if RUBY_PLATFORM =~ /mswin|bccwin|mingw/
  class File
    remove_const :ALT_SEPARATOR
    ALT_SEPARATOR = "\\"
  end
end

I understand this change was introduced on ruby_1_8 by my request:

http://redmine.ruby-lang.org/issues/show/2531

But that is all I can dig and understand around the issue.

Sorry for not been more helpful.
