Title: Guard against undefined XSL_SECPREF_WRITE_FILE.

Related to #800 at phing.info. Usage of constant XSL_SECPREF_WRITE_FILE
in older versions of php produces an undefined constant warning.
Depending on php runtime configuration this can lead to a fatal error as
some php environments will install a error to exception routine.
