Very large files

[John Willis]

Howdy,

I have a large VS 6.0 C++ program and I'm running it under WINE under Redhat Linux. 
Everything works fine, but it doesn't handle file sizes greater than 4gb like it can running 
directly under Windows XP. 
I've tweaked everything that I can find that seems to deal with file sizes. 
Is there a problem with WINE itself handling very large file sizes?

Thanks in advance,
John
