Hi, I have kindof similar situation, so i'm curious about how you did that. 
Did you make your own custom external script (calling diff), or is there a 
standard way to do it ?
Also, my generated headers sometimes differs only by a C comment (a timestamp 
in fact), so do  someone know if there is a customizable way to compare files 
for uptodateness ?
