Summary:                    strsep broken in 0.9.29, works fine in 0.9.28.3 and
earlier
Description: 
The changes made to the strsep code have caused it, in my application, to
not return NULL after it hits the last token. For instance the following
code will loop forever, continuously returning the last token (1 in the
example) once it has walked through the string:

copyptr = "2:45:29:325:0:TEST:1"; // Just an example
while ( (token[i] = strsep(&copyptr, ":")) > 0 )
{
...
}

Earlier versions did not have this problem. I compiled uClibc with gcc
4.1.2 for i486 AMD Elan with the following options enabled in .config:
