[GRASSLIST:2162] Vect.h: problems from external code

I am trying to program GRASS externally, from python, using the weave  
module for integrating C code. It essentially allows me to run compiled  
C code from within python. However, when the C code gets compiled,  
including Vect.h causes problems (see below). None of the other modules  
cause errors -- just Vect.h. I'm wondering what I might be missing or  
doing wrong.
