php4-4.3.7-1

[JJB]

When I was running under php4-4.3.6-1 everything worked.
Today I upgraded to php4-4.3.7-1 and I get this error.

I have no T_LNUMBER field at all.
Sim49.php has not changed. Line 98 is the way it's always been.

Can somebody translate this error message into something I can use
as pointer of what to look at in debugging this problem?

Parse error: parse error, unexpected T_LNUMBER in
/usr/local/www/data/sim49.php on line 98
