Well, sometimes, *not* always.
And *only* for Windows, it was fine on other platforms.

*No*! It was *not* changed, as I already told you in my last reply on 
the list. I aimed at and still have not found the time. And again, only 

I fear you do not understand what I meant: I am just stopping to build 
some packages in parallel. Other stuff is not affected, hence nothing 
you or this list need to worry about.
I should not have told you, as I understand now. I just tried to give 
you an explanation why your packages failed twice in the past due to bad 
I just should keep quite in future and answer with a simple "no idea" 
given all the information and even internal guesses are reported in a 
different context and used for list-wide speculation in the end.

No, that's not the reason: the change has not yet been implemented.

Why should the CRAN team care about it?

Really, given my lack of time and your annoying posts to the lists 
containing misleading information, I probably should stop to care about 
your package at all. There are > 2000 other packages and some more 
important tasks to tackle. Consider the CRAN team would take so much 
time for each single package ...
