damn me! *really* sorry for this.
Ingo, do you use some script for this checking? if yes - could you share it? ;)
(i think it's not really hard to write myown, but your one is really preferred
;)

nah, this happens all the time for me too - that's why i run a script 
over cleanup patches.

sure, pick up the script from:

 http://redhat.com/~mingo/misc/q-size-obj-compare

it depends on having the patch in a quilt queue. (and it's really sucky, 
no error checking, etc.)

just run it - it picks up a modified .c file and compares that. If you 
modify multiple files and want to check another one, give that file as 
an argument to the script.

yep, but i don't want to put additional work on developers so i must
review the patches i'm sending *several* times at least! so that is my
fault ;)
