Details:

Reading uninitialised variable does not cause compile error. I was reading
"Programming C#" from Oreley. Example3-2 on page 27 is an example of using an
unitialised variable, see attachment. According to "Programming C#" I am
suposed to get this error message when compiling:

3.1.cs(6,55): error CS0165: Use of unassigned local
variable 'myInt'

But cscc version 0.7.4 compiles without any error, and the program runs
without crashing:

$ cscc Values.cs
$ ilrun a.out
Uninitialized, myInt: 0
Assigned, myInt: 5

According to "Programming C#" it is not legal to use an unitialised variable
in C#.

Example3-2 is attached as Value.cs.
