Yes, I know when they shouldn't be used. But I've discovered that they allow
me to work around various issues which come up during autoconfiscation, in a
really straightforward way. So I'd like to introduce these two variables for
my future use.
'pwd' technically conflicts with a variable in 'configure', but that variable
is defined to exactly the same thing (with no 'cd's in between), so...

* configure.in: Introduce variables 'pwd', 'abs_srcdir'.

Why not call it abs_builddir to be consistent and less confusing (wrt
$pwd)?
