Subject: Re: Windows XP : RubyInline 1.0.4 Released! (fwd)

Experts,

After a couple of wrong starts (forgot to set the .NET settings ;-)) I was
able to get RubyInline working on my Windows XP (Home Edition). See results
below:

C:\>ruby example.rb
RubyInline 1.0.5
Type = Inline, Iter = 1000000, time = 4.33600000 sec, 0.00000434 sec / iter

Thanks a lot Park, nobu and Ryan for your attention.
My final request is that these changes (see Park's version below) be
refactored into the new 1.0.5 release (enhanced security) that Ryan came out
with.

TIA,

-- Shanko
