I don't see why there's need for insults when one asks politely.
Of course, 'rather detailed' is always a rather subjective assessment.
Wonder no more. The original response:
* doesn't specify what additional make arguments/environment vars should 
be set if I'm to run make from ./xen/ rather then ./
* doesn't make it clear what you mean by "intended target". I suppose 
you weren't suggesting to manually run make for *each*
source file I want to preprocess one by one, since I was asking how to 
do that for all sources ('make dist-xen'...)
Thanks anyway,
Corneliu.
