I've committed your patch, my MEGA thanks!  

I would really like you to have a commit bit.  Are you willing?

Matz, what do you thing?  He is a great all-round player; his
contribution to Ruby includes deadlock issues (his patches was
applied by kosaki), windows issues (accepted by usa and naruse),
algorithmic issue (accepted by mrkn and me), documentation
issues (by nobu), etc.

Hello,

After r37655, I noticed a failing test on RubyInstaller CI for x86:

 test_bsearch_for_float(TestRange) [C:/Users/Luis/Code/ruby/ruby/test/ruby/test_range.rb:392]:
 Expected -1.7976931348623157e+308 to be >= NaN.

This do not fail on x64, both running with GCC 4.7.2

I don't have Linux test results to compare at this time, but wanted to raise awareness of this issue.

Thank you
=end
