SubjectRe: PCI Express support for 2.4 kernel
Hi!

> I did not found this feature in standard.

I did :-)  C99, section 6.7.8 "Initialization", constraint 10:

"... If an object that has static storage duration is not initialized
explicitly, then:

   - if it has pointer type, it is initialized to a null pointer;
   - if it has arithmetic type, it is initialized to (positive or unsigned) zero;

..."

> "use of uninitialized variable".

Yes, such warning exists, but only for automatic variables.

				Have a nice fortnight
