Obviously.

But how could the trunk users to test a new patch if it breaks the 
bootstrap?

I thought that passing the bootstrap was the minimal request for 
submitting a patch and that this would be reached if all start with the 
same conditions in bootstrapping.

Sorry if I has been wrong.

I think that on my backup DVDs I have working build until two months ago.

And if I build so often, it is to avoid the pile-up of bugs (when they 
are present) that would make hard to solve, mainly on Cygwin, on which 
no cygwin-guys take care of them.

Sorry newly for the noise,
