SCC error

[N. Vienne (thales)]

Checking the EDF-like scheduler with scc raise an error :

C:\Documents and Settings\T0081686\Bureau\Josefil>scc EDF.sc

Parsing error : Line 5, tasks.start_time, Undeclared Identifier

Content of EDF.sc :

start_section:

dynamic_priority : array (tasks_range) of integer;

priority_section:

dynamic_priority := tasks.start_time + tasks.deadline

+ ((tasks.activation_number-1)*tasks.period);

election_section:

return min_to_index(dynamic_priority);

It's not critical since Cheddar seems to work correctly with the defined scheduler, but
the remaining lines are not checked.
