RE: Source lines out of sync with instructions

[Tim <Tim@deltacompsys.com>]

Thanx! I tried again just to be sure by actually deleting the obj file
rather than using make clean.  Still has the problem.  

I also tried deleting the app and objs and typing out gcc -ggdb -Wall
... on the command line with the same results.

If the problem is a bad build I'm at a loss to understand what I'm doing
wrong...

Any other thoughts?  THanx!
