there are different excuses, reasons for everything, as example I use
WinXP, while:

1) it is capable to start multiply instances of "norton commander" !!!
well sure yet not very good at it, but manageable.

yes I have looked at midnight commander too, but I still stick
to my old tools, eg the original NC (or actually its clone FAR)

Easy enough to do that with LD_PRELOAD in Linux. (.so injection)
Interesting idea!

Assuming you can get the windrv header file, although I think you can
probably reverse engineer it anyway.

Go to windriver website and download the evaluation version. It
includes the header files.
