Things get really interesting with code like this:
class RelationPages
{
public:
vcl* rel_pages; // vector of pointer page
numbers
SLONG rel_instance_id; // 0 or att_attachment_id or
tra_number
Attachment's id and related functions use SLONG and maybe they don't need
more, but the same var can contain tra id. And then
// global temporary relations attributes
RelationPages* getPages(thread_db* tdbb, SLONG tran = -1, bool allocPages =
true);
....
bool delPages(thread_db* tdbb, SLONG tran = -1,
RelationPages* aPages = 0);
Those functions use -1 to indicate a special condition.
I can attempt the change to unsigned, but I don't know if Firebird will
explode in flames.
