[fpc-pascal] Operator not overloaded

[Thomas Kurz]

Thank you very much, declaring the operator within the record does indeed solve the issue.

Just to be sure in case I might need it some day: Does this mean, if I need e.g. a comparison operator for a specialized TPair, I would declare a record class helper and define the operator there?

Global operator overloads need to be available at the time the generic is
*declared*, not *specialized*. That is one of the reasons why advanced
records were introduced.

So you need to declare your operators as part of your record.
