I am using Microsoft C 5.1.  I have a variable defined before the first
function declaration like this:

int crc_flag;

As soon as I enter the first function, CodeView reports that the value
of the function has changed, from 1 to 0.  The variable is not declared
inside the function, and is not an argument in the function call.

This seems wrong, based on my understanding of C.  What should be
happening?  -David-
