Patch by Robert Scheck <robert@fedoraproject.org> for apachetop <= 0.12.6, which
adds some includes in order to have a real change to get MAXPATHLEN defined with
a valid value. Once MAXPATHLEN really gets filled with 128, it will just cause a
buffer overflow.
See Red Hat Bugzilla #446199 (https://bugzilla.redhat.com/show_bug.cgi?id=446199)
for more information. This patch should solve the mentioned bug report and should
be sane enough to get included by upstream of apachetop for the next release. It
is important to run autoheader before ./configure to get these changes activated.
