Actually, that should be done to the gerber file.  The *.pcb 
file should adopt one convention, holes are the finished size.  
Then the gerber file should be altered to the vendor 
preferences.  That way the *.pdc file remains vendor 
independent, and the vendor could use it when needed.

My students used pcb for a course project last spring, and 
discovered this problem the hard way.
