[fpc-pascal] Initializing a record-type variable to get rid of the false-positive compiler hint

Thank you very much Jose, that's a detail explanation. Forget my wrong observation before.

Hello FPC-Pascal,

Rec parameter is qualified as "out" so, the enter values is
non-important and the compiler will not generate the "non initialized"
hint.

The $PUSH pushes in fpc stack the current settings about hints,
warnings, alignement, etc, then I change the hints to off, because
FillByte could produce (not sure with formal parameter) the hint
message and then $POP restores previous settings about hints and other
directives.
