[IronPython] IronPython.Modules.dll bug when access from Delphi

[Lukas Cenovsky]

Of course the bug was not in IronPython :-) Thanks Dino for helping me 
find it!

Check my question on StackOverflow 
(http://stackoverflow.com/questions/2048540/hosting-clr-in-delphi-with-jcl-example) 
how to work with .NET from Delphi Win32. Beware especially of different 
floating point exceptions behavior in Delphi (that was my problem). You 
have to call Set8087CW($133F); before any work with .NET. After that, 
it's only matter of creating IronPython engine etc.
