Hi,

I had the same problem. This code compiled perfectly under gcc 2.7.2.
Seems that egcs is a lot stricter on variable scope. The variable status
is not initialised at the beginning of the function but just before use
in an if {} statement. 

There are two ways to fix this that i found.

1. Define status at the beginning of every function that it is used
2. My personal hack a global variable call status ;) I know this is
really bad coding but didnt have time to fix it properly.

hope this helps
