+As of JPEG-9, the type 'boolean' is an enumeration, but since glib defines
+TRUE and FALSE as numeric constants and this is C++, they need to be explicitly
+casted.

+In the following file, we also need to reverse header include order: JPEG needs
+to be included before Glib, which is included by "abiword-garble.h" for this fix
+to work.
+
+The JPEG header needs the types FILE and size_t, we can get them from cstdio.
