Hi,

thank you very much for your reply and your detailed questions. I try to answer 
them as good as possible.

Here we go.

No, we changed nothing. Should we ?

I read this, but for my problem it did not help me very much.

In the whole project directory (and all subdirectories) you find neither a *.P* 
file nor a .deps directory.

No, it does not exist, so it contains nothing.

No. We wrote an autoconf macro to rerun configure automatically in 
obj/gcc_2.95.3-release-GL during a configure run which is started in the 
project root directory. The users like this. So the only command you have to 
start is

./configure

in the project root directory.

Beside that this macro creates for every compiler version and every debug resp. 
release version and for every OpenGL resp. Mesa version of the project an own 
object directory which resides in the directory 'obj' (gcc_2.95.3-release-GL is 
only one of them). After the creation it makes a cd into the created directory 
and starts 'configure' in the project root directly from the macro (more or 
less recursively).

I think the last option (even something else). I hope that the above statements 
makes things clearer.

I did it and run './configure' but it prints nothing.

On my system, this does absolutely nothing.

We uses sed 3.02
