description:
Hack around misuse of fpos_t. Fix some code that assumed fpos_t is a
4-byte integer type. If this code ever worked on NetBSD, it was only
by accident. PKGREVISION++ for the fixes.

+Hack around misuse of fpos_t. Fix some places where the code assumes
+fpos_t is a 4-byte integer (it has always been an 8-byte integer on
+NetBSD...) Cannot fix the core assumption that fpos_t is an integer,
+though, so work around it.
