Your error message seems to be at line 189, whereas in my mud.h EXT_BV (extended_bitvector) is defined at line 344. Thus you are using it before it has been properly defined.
In my file affect_data is at line 1295, have you moved things around?
Wow, yea. I didnt realize I had moved the function without its definitions. I had done it once or twice more.. ah well, comes with reorganizing code. Thanks for your help!
Now I can get down to work with the other.. 1500... errors of mine, heh =)
