Parallel processing support in Windows?

[dmitry-brok]

AFAIK this -w option should work since version 1.5.0.
>>Parallel processing support added. Use option -w max or --workers=max to enable.

I built the latest jpegoptim under Ubuntu and the -w worked just fine
This Windows build seems to have no this option enabled

I really need this parallel processing under Windows ... Is there a way to get it?

Current parallel processing implementation relies on fork() system call, that is not present in Windows (or has it been recently added?), so it's not trivial to enable this feature on Windows...

Using threading (vs. current forking) might be one option, but I seem to recall that libjpeg library was not thread-safe.... (?)

Okay I got it
So it's not that easy
I have to stay with linux version though

Thank you

I just wrote a PowerShell script on Windows to implement this feature.
