Hi Sander,

thanks for the report.  Your reports always make for some good thinking.

Yes, in this case you have to pass the variable to config.status,
as hinted in the manual, but probably not clear enough:

So this should work:

Note that the weird quoting works because the third argument is expanded
inside a here document.  FWIW, I'd recommend using a different variable
than PACKAGE_VERSION to avoid potential clashes.

I don't think we will fix this (because I think fixing it /right/ is
probably hard), but if you have suggestions (or a patch) on how to
improve the manual here so that it is clearer, that would be nice.
