Build of GDC on FreeBSD 14 (CURRENT) fails. Here is the error message I get

I managed to fix the issue for the FreeBSD ports by updating the values of
__FreeBSD_version in libphobos/libdruntime/core/sys/freebsd/config.d. Please
see the patch in
https://cgit.freebsd.org/ports/diff/lang/gcc11-devel/files/patch-libphobos_libdruntime_core_sys_freebsd_config.d?id=f61fb49b2e76fd4f7a5b7a11510b5109206c19f2
, which introduces a new value for FreeBSD_14 and, while here, updates the
values for the other supported FreeBSD version.

    d: Update __FreeBSD_version values [PR107469]

    Update __FreeBSD_version values for the latest supported FreeBSD
    versions. In particular, add __FreeBSD_version for FreeBSD 14, which
    is necessary to compile libphobos successfully on FreeBSD 14.
