Upstream has released link:https://gcc.gnu.org/gcc-13[GCC 13].
As announced in the past status report, I plan to attempt an update of GCC_DEFAULT right from the first GCC 13 release, thus much of this quarter's work has been in preparation of this.

With the release of GCC 13.1 (first GCC 13 release: I remind that GCC counts minor version releases starting from 1), two new ports have been created in the ports tree:

* package:lang/gcc13[], tracking GCC 13 releases;
* package:lang/gcc14-devel[], tracking snapshots from the new GCC 14 upstream branch.

==== The *-devel ports

Support for .init_array and .fini_array has been enabled.
FreeBSD supports both since commit gitref:83aa9cc00c2d83d05a0efe7a1496d8aab4a153bb[repository=src].

The default bootstrap option on i386, amd64, and aarch64 has been reverted from LTO_BOOTSTRAP to STANDARD_BOOTSTRAP:

- LTO bootstrap produces too many failures on the package builders for those architectures
- LTO_BOOTSTRAP remains available for users who want it.

Those changes will be forwarded to the production ports.

==== The production ports

Upstream has released GCC 13, for which the new port package:lang/gcc13[] has been created.
GCC 11 and GCC 12 have been updated upstream and a new release of GCC 10 is planned.
All corresponding ports now need to be updated.

To ease the work of both ports maintainers and users, I plan to test and update together all the following changes:

* updates of package:lang/gcc10[], package:lang/gcc11[], package:lang/gcc12[];
* update of GCC_DEFAULT to 13;
* enabling of .init_array and .fini_array on the production ports;
* switching back from LTO_BOOTSTRAP to STANDARD_BOOTSTRAP on the production ports.

This will provide the following advantages:

* more testing with less exp-runs;
* fewer builds for ports users.
