Ok, it is defined by POSIX, I will adjust the commit message.

I received an error report from someone else which regularly builds 
Newlib and this use of awk broke the build. I don't know the exact

Independent of the POSIX compliance of the existing code I think the 
change to use the return value of split() doesn't hurt?
