Hello, I sah in the mt_gem.h that NIL is defined with 0. But that is not correct it must be -1. For example the define is used in the object structure if ob_head have no kind object. The problem is that it looks like that this is since many year and I am surprised that I am the first one who find this. So what is to do? Change it in the header and hope that nobody use NIL and wants 0 or let it be. And hope nobody want -1. Gerhard
