[fpc-pascal] How to solve "variable does not seem to be initialized" compiler hint.

[Rainer Stratmann]

For me a variable is initialised when it passes a procedure/function which has 
a  var declaration in the parameters.
May be it is possible to make a compiler switch like
$PASS_VAR_NO_HINT ON
instead of globally
$HINTS OFF

Then all variables wich passes for example the fillchar procedure are 
initialised if the switch $PASS_VAR_NO_HINT ON is set.
