Hello,
there is wrong statement regarding the characters which are parsed in 
the input string:

"In locales other than the "C" locale, other strings may also be 
accepted.  (For example, the thousands separator of the current locale 
may be supported.)"

It is not possible to use other strings - see stdlib/strtol_l.c in 
glibc. The patch is attached.
