If there are actual problems found by the lint output, we'd, of
course, be interested, and they should be filed in bugzilla but I don't
think we are particularly interested in the full output.

The general policy is that for GTK+/GDK/Pango we are not interested in
"problems" of the nature:

 int foo = strlen (string);

unless there is some probability that the string could actually
usefully have 2 billion characters in it, and casts to suppress
64-bit lint warnings:

 int foo = (int)strlen (string);

Are also not really acceptable, since they make the code much
more visually cluttered.

(We did go through and fix up GLib to be clean in the use
of size_t where necessary)

Also, no API changes that involve changing the width of arguments
can be made at this point.

(http://bugzilla.gnome.org/show_bug.cgi?id=56652 is a GTK+ bug that
was filed in this area earlier; the corresponding GLib bug is:
http://bugzilla.gnome.org/show_bug.cgi?id=53764.)
