Dear Tomas,

Thanks for the swift reply!

OK, then I should do `quilt pop -a` before the second compilation,
right?

But that leads to another error message:

(Of course, I am not simply recompiling, but, I am making a patch via
quilt.  But since this is me doing it, the patch is not perfect first
time and I have to go over it again.  I
have started from freshly downloaded sources, but that becomes
cumbersome and I would rather like modify the patch instead of starting
over.  I am now happy with my patch, but still would like to know how to
do such things without starting over....)

Best,
Andreas
