Merge two patches already upstream:
- use a more compact encoding for reals by dropping trailing zeros after
  the decimal point.
- ensure the BaseFont property of the standard PS fonts is preserved.

Bump revision.
Do not default to inotify support on SunOS, libinotify is not yet ported
to that platform.
PKGVERSION is an internal variable, so use something else.
Add visibility wrapper around ios and ostream. Don't use false as null
pointer.
Fix header guard.
Explicitly depend on py-expat. Bump revision.
Fix build on SunOS by disabling the isainfo bitness check (patch lost
in previous package update).
