>Description:
Building "sysutils/apcupsd" on NetBSD/sparc-9.0_BETA fails linking with:
[...]
LD src/apcupsd
ld: /usr/lib/libsupc++.a(eh_throw.o):(.text+0x78): undefined reference to `__gnu_cxx::__exchange_and_add(int volatile*, int)'
I have an old binary package from the last time I built apcupsd on sparc.
It reports OS_VERSION of 8.99.26. So whatever the gcc/g++ version and
libraries in use at that time, it worked fine.

The same failure occurs with -current (9.99.17).

this is likely due to sparc lacking native CAS. i have no idea
if there is a simple or workable fix...

As there was no problem in the past (at least back to netbsd-6 through
8.99.26), there must have been something that served that purpose.
The claimed missing symbol is perhaps a GCC internal implementation
substituted for missing hardware functionality? In case it's relevant,
the GCC in use for 8.99.26 appears to have been GCC-6.

With sparc-current (9.99.17) switched to GCC 8, the same failure occurs.

I built HEAD from 20190209093400Z (8.99.34 just before sparc was switched
to GCC7), showing:
$ gcc -v
[...]
Target: sparc--netbsdelf
[...]
gcc version 6.5.0 (nb4 20181109)
In this state, "sysutils/apcupsd" built successfully on sparc.

this appears to be due to not using the right atomicity.h.
we'll need some mknative updates i guess. this problem also appears
to be not sparc specific, but only triggers there...

actually, atomicity.h is properly handled. it's just that sparc
wants it in libsupc++ and it's only in libstdc++.
the hack below may help.
John, i'll see about testing myself, but if you can try a test
(you should only have to reinstall libsupc++.a) that would be
great. thanks.

I've applied the patch and rebuilt. The two machines most likely to
perform the test are currently occupied with long-running tasks. As
soon as one or the other is free, I'll be able to test.

Actually, I've applied the patch to -current as well, so once I can get
sparc-current rebuilt and updated, I have a machine already available on
which to test.

My sparc-current system (9.99.56 from sources of 202004190030Z) with
the patch applied successfully built "sysutils/apcupsd".
One of the other systems is nearing the end of its long-running operation
so I'll be able to test netbsd-9 with the patch soon.

I've now successfully completed the build of "sysutils/apcupsd" on
netbsd-9/sparc.
Unfortunately, base-system 'dhcpcd' seems to be broken after a release
build and update with this hack in place.

OK, i'll commit and request a pullup. thanks for
testing.

i suspect this is due to dhcpcd updates in -current.
it is extremely unlikely dhcpcd uses libsupc++, which
is only used in some special cases of C++, and dhcpcd
is not a C++ applicaiton.

But why did it suddenly also appear in netbsd-9?
In both cases, it only appeared after applying your hack/patch for this
PR.

yes - dhcpcd was changed on -9 recently too..

I've updated -current post-commit and am building a release now.
Once done and target updated, will test-build the trouble package.
Will also need to wait for pull-up to netbsd-9 to be completed and
perform the same steps as above.

The problem package ("sysutils/apcupsd") now builds without error on
sparc-current.
Just waiting for the pull-up to netbsd-9.
