Hi,

	Since GCC 2.8.1 (and perhaps a bit earlier) the authors have begun 
using "#define NULL __null".. One problem arises:

If #include <stdio.h> occures anywhere throughout my code (and since 
it is a very common library, it obviously does) I get the following 
message telling me that stdio.h tried to redefine NULL (which was 
previously defined as __null).. The only way I found around this is to
stick an "#ifndef ... #endif" block before "#define NULL 0" command in
<stdio.h>.. But what I'm wondering is, is this conflict suppose to 
exist? Is something wrong with my configuration? What's going on? :)
