Antwort: Re: bug when redirecting mingw32-make output (w32/sub_proc/sub_proc.c)

[Roland Puntaier]

The buggy behaviour turned up, when starting mingw32-make
from an application with the mingw32-make output redirected to that application.
I made a minimal application to reproduce the behaviour.
The code was in C# and I included that code in my previous mail.

But using CreateProcess with standard output redirection
in C++ should lead to the same behaviour. 
There is an example in msdn (search for "CreateProcess redirection"),
where one might replace the child application with mingw32-make.

As makefile you can use anything that lets mingw32-make
start a new console application.
