The reason is in the way PmWiki's SDV function works. Short answer:

Try

SDV($calendar_weekstyle,0);
SDV($calendar_datestyle,1);
SDV($calendar_months_number,4);
SDV($calendar_month_wrap,2);
SDV($summary_only,false);
include_once("local/wikilog.php");

That is, move the include *after* the SDV settings.

Longer answer:
The SDV function looks to see if the variable being set already
has a value. If it does, the value is unchanged. So, wikilog.php
sets its defaults using SDV; thus if an administrator writes

$calendar_weekstyle = 0;
include_once("local/wikilog.php");

the local setting will over-ride the default. Similarly, an
administrator can write

include_once("local/wikilog.php");
$calendar_weekstyle = 0;

and again the local setting over-rides the default value.

In general (this is not always possible, but it's a good
rule of thumb), cookbook scripts use SDV to set default
values and local/config.php scripts use $v = 'value';
assignments.

I will update the calendar page to clarify this. Thanks for
pointing it out.
