NP. It is just very usual misunderstanding so I wonted to highlight and ensure.

Windows. They are very bad on living with .bats.  Also we have duplicated  codebase for bat and sh, 
which is already now making people unhappy and confused (the email from Bundit). I really don't know 
any other way how to make windows and linux launchers based on shared code.

Ideal world I can imageine, is to remove bat launchers, and compile sh ones to standalone binary 
(highlight no cygwin)

Yes. I do the same, and I really wish to continue support for them, at least until native ones 
proves themselves (two three years).

I hope, that crosscompialtion will not be needed.   If you built it on linux, and it works, it 
should work also after built on windows and vice versa.
Yes, with bats, you could probably distribute them to final windows environemtns. With crosscompiled 
binaries... I never trusted them... Is even solid crosscompialtion linux-windows possible?

Thats true. So please, focus your work on sh/bat. From sh, it will bubble to rust ones (unless we 
discard them  if different approach will be suddenly taken)
