[uClibc]inet_pton for AF_INET6 broken (macro side effect)

[Ronald Wahl]

Hallo,

here is my daily bug report. ;-) Today: inet_pton / tolower

inet_pton is broken for AF_INET6 addresses. The reason is the following:

This piece of code from inet_pton breaks since tolower is implemented as
macro and its argument is evaluated more than once:

        ...
        while ((ch = tolower (*src++)) != '\0') {
        ...

Please fix.

thx,
ron
