[fpc-pascal] Why has the tkFloat default value changed?

[Mattias Gaertner]

Hi,

In FPC 3.2.0 the default "Default" value of a single/double property
has changed from $80000000 (fpc 3.0.4) to 0.

This breaks TWriter.
The $80000000 means the property has no default value.
Now FPC 3.2.0 no longer writes a property if the value is 0.0, no
matter what the stored function says.

For example:
property S: Single read FSingle write FSingle stored IsSStored;

FPC 3.0.4 TWriter does write S if S=0.0 and IsSStored returns true.
FPC 3.2.0 does not.

I can't find this change in
