ssize_t must be a signed type

[gregory benison]

The most recent g-wrap code (from
address@hidden/g-wrap--dev--0) wraps ssize_t but appears not to
allow negative values.  This breaks some functions in guile-gnome;
for example this call will fail:

(gtk-ui-manager-add-string ui str -1)

but it should succeed since -1 is a valid value for the third argument.  A patch such as the following resolves the issue.
