slight api change: the getkey and free functions now take a user data parameter (which is an aditional parameter to Hash_New. cmd.c, cvar.c, quakefs.c: clean up the resulting errors. pr_edict.c: use hash tables for lookups of function, global and field definitions. should speed things up a bit, ESPECIALLY when type checking is enabled.
