From 45d592deb685e106e20933502bbecda04ab73d75 Mon Sep 17 00:00:00 2001
From: Michele Calgaro <michele.calgaro@yahoo.it>
Date: Thu, 1 Jan 2026 19:03:47 +0900
Subject: Remove usage of TQ_FULL_TEMPLATE_INSTANTIATION and
 TQ_DUMMY_COMPARISON_OPERATOR. The #defines were used for some very old
 compilers which had issues with template instantiation. We are now using
 c++17 compilers, so this is unnecessary.

- compilers which follow outdated template instantiation rules

- a TQValueList of this type is instantiated. It's not actually
- used in the list, though. Hence the dummy implementation.
- Just in case other code relies on it we better trigger a warning
- mandating a real implementation.
