T_LNUMBER?

This is an error I’ve not run into before, and have no idea what I should be correcting to make it work.

Opening my blog homepage, http://globalmemo.org/weblog/,

I receive the following error message:

Parse error: syntax error, unexpected T_LNUMBER in /home/tfleming/public_html/weblog/wp-includes/formatting.php on line 98

Here are lines 96-111 of said file, with line 98 in bold:

function seems_utf8($Str) { # by bmorel at ssi dot fr
for ($i=0; $i<strlen($Str); $i++) {
if (ord($Str[$i]) 0x80) continue; # 0bbbbbbb
elseif ((ord($Str[$i]) & 0xE0) == 0xC0) $n=1; # 110bbbbb
elseif ((ord($Str[$i]) & 0xF0) == 0xE0) $n=2; # 1110bbbb
elseif ((ord($Str[$i]) & 0xF8) == 0xF0) $n=3; # 11110bbb
elseif ((ord($Str[$i]) & 0xFC) == 0xF8) $n=4; # 111110bb
elseif ((ord($Str[$i]) & 0xFE) == 0xFC) $n=5; # 1111110b
else return false; # Does not match any model
for ($j=0; $j$n; $j++) { # n bytes matching 10bbbbbb follow ?
if ((++$i == strlen($Str)) || ((ord($Str[$i]) & 0xC0) != 0x80))
return false;
}
}
return true;
}

Any help would be greatly appreciated!
