Hi Lutz,

As of 8.7.5 there is new functionality in the 'process' statement: the stderr is redirected by default to stdout.

This creates a problem when communicating by 2-way pipes. It means that errors caused by the child process disturb the regular communication. My GTK-server does not show the GTK GUI anymore, when GTK errors happen disturbing the channel.

For Linux/Unix I can redirect stderr to a 3rd pipe. However, according to the docs this is not possible for Win32.

It means it would break all compatibility in situations where newLisp wants to communicate with a child process, and this child process generates errors.

For the GTK-server this can be solved by importing the DLL version now. But for other situations I guess there is a problem.

Is there a way to implement this 3rd pipe for stdout also for Win32?

For Win32 the treatment of standard error has never changed, it always was redirected to stdout.

The additional option to redirect std-error to a differemt channel was only added to Linux/Unix.

Ok thanks!
