fails to build with GCC 14

[david-geiger]

Hi,

Current source code fails to build with GCC 14 with the following build issue:

In file included from /home/pterjan/rpmbuild/BUILD/tora-3.2/extlibs/dtl/dtl/dtl.hpp:44,
from /home/pterjan/rpmbuild/BUILD/tora-3.2/src/editor/todifftext.cpp:39:
/home/pterjan/rpmbuild/BUILD/tora-3.2/extlibs/dtl/dtl/Diff.hpp: In member function 'void dtl::Diff<elem, sequence, comparator>::enableTrivial() const':
/home/pterjan/rpmbuild/BUILD/tora-3.2/extlibs/dtl/dtl/Diff.hpp:166:27: error: assignment of member 'trivial' in read-only object
166 | this->trivial = true;
| ~~~~~~~~~~~~~~^~~~~~

This PR fixes build: cubicdaiya/dtl#18

Also this PR antlr/antlr3#224 is needed to fix build with embedded libantlr3cpp-3.5.3!

You probably shouldn't accept this patch, as it changes the program logic.
I've added several patches to PR #168
which fix not only this bug but also other related ones(for GCC-14 & GCC-15).
I also recommend reading #166

Always this build issue with latest git qt6 branch and your PR #168:

Not tested with trunk qt. Only qtbase-6.10.2 .
How version gcc? /me test with gcc-14 (Gentoo 14.3.1_p20260213 p5) & gcc-15 (Gentoo 15.2.1_p20260214 p5)
Update 1.
It turns out I didn't include a patch from the previous ones (not made by me).
I'll try adding it today. It's a simple patch.
In file dtl/Diff.hpp b/dtl/Diff.hpp
replace
void enableTrivial () const {
to
void enableTrivial () {

[atlant2011]

Apply patch for fix "void enableTrivial () ". PR #168 refreshed.
Test it's.
