There are often area's where the standard says it is not required or 
undefined yet a majority of vendors DO allow it as is the case here I 
believe.
In effect it becomes a de-facto but unofficial standard. Remember we as 
programmers tend to be lazy,
if it works on most compilers we tend to expect it to work on all of them.
