An SGML entity [0] or an xsltproc stringparam [1] looks viable. Question is
how to calculate the number of decades in the Makefile. It's trivial in SQL :)
=# select extract(decade from now()) - extract(decade from date '1986-01-01');
?column?
----------
4
(1 row)
=# select extract(day from now() - date '1986-01-01') / 365.25 / 10;
?column?
--------------------
3.7472963723477071
(1 row)
