Gedare, I support this.

Gedare, I agreed.

Ralf, based on what ? Gedare's link shows the amount of lines doubles.

Does this mean the bootstrap is going away as a result of this ?

Could you explain this ? I find the complexity of the autoconf and 
automake set up we have in RTEMS difficult to follow so I fail to 
understand how I am support to come to this conclusion.

Could you please explain this ?

Gedare was commenting on the issues with the files not in git.

I am sure but other are struggling with the change and reason. The nice 
thing about git is a clone could have been set up and what you propose 
tested and evaluated.

We can see this. You I would like to see a discussion about this issue.

I have no interest in being an autoconf or automake expert. I wish to 
development RTEMS. Maybe if you have given us a little more information 
about the purpose, reasons and some examples then this might have been 
avoided. Giving us something to play with would have helped. Abusing us 
helps no one.

No one who posted agreed with the change. You should have respected that 
and provided the detail and explained the case. Just pushing the change 
in the repo is not

Could you please provide documentation on how we are suppose to use this 
? For example can we mix generated files from different hosts ? Does a 
change in any autotools require all generated files to be updated ? 
There are many more questions.
