Heh, the webpage says %pure-parser is also deprecated and the replacement
is:

%define api.pure

http://www.gnu.org/software/bison/manual/bison.html#g_t_0025define-Summary

(It says the 'full' option was introduced in 2.7 but doesn't say how far
back the 'true' option (same as no option) works; Ubuntu's oldest is 2.3,
which probably works since other %define api.* things were introduced in
2.3 but there's no mention of 'true'...)

This patch is probably fine as-is but we might be back here again soon.
