The tsvector code is printing a pointer difference as an integer,
generating the following warning:
tsvector.c: In function 'tsvectorin':
tsvector.c:225: warning: format '%d' expects type 'int', but argument 2
has type 'long int'
I was thinking the %td specifier wasn't well supported enough, so I simply
used long.
