Inconsistency in /usr/include/c++ same version of c++ different releases

How these builds are being generated ? Is this only for ARM ?

Last days I tried to enable some pins in BBB ARM builds. I ran out of options with
Code: 
FreeBSD generic 13.0-CURRENT FreeBSD 13.0-CURRENT r351363 GENERIC  arm
Then I start downgrading, installing back builds. I end up using.
Code: 
FreeBSD beaglebone 11.3-RELEASE FreeBSD 11.3-RELEASE #0 r349754: Fri Jul  5 03:41:31 UTC 2019     root@releng2.nyi.freebsd.org:/usr/obj/arm.armv6/usr/src/sys/BEAGLEBONE  arm

Before downgrading I built my application (C++) and everything built OK ( ver 13.0).
Now using ver 11 from 2018 I cannot build the c++ app. I get std++ errors. Tough the (g++) c++ versions are 8.0.X on both systems.
The /usr/include/c++/ on both versions shows

Code: 
[marius@beaglebone /usr/include/c++]$ ls -l
total 8
drwxr-xr-x  7 root  wheel   512 Jul  5 03:41 4.2
drwxr-xr-x  5 root  wheel  3072 Jul  5 03:42 v1

[marius@beaglebone /usr/include/c++]$


[root@generic /usr/include/c++]# ls -l
total 8
drwxr-xr-x  7 root  wheel   512 Aug 22 03:48 4.2
drwxr-xr-x  5 root  wheel  3072 Aug 22 03:49 v1
[root@generic /usr/include/c++]# uname -a
FreeBSD generic 13.0-CURRENT FreeBSD 13.0-CURRENT r351363 GENERIC  arm
[root@generic /usr/include/c++]#

Though on a closer look the files differ.

Code: 
[marius@beaglebone ~/cpp13/include]$ diff -rq ./c++/ /usr/include/c++
Files ./c++/v1/__errc and /usr/include/c++/v1/__errc differ

When you do a source upgrade/update make sure to also run make -C /usr/src delete-old and make -C /usr/src delete-old-libs to remove old stuff (set BATCH_DELETE_OLD_FILES to automate it).
