Something missing perhaps?

[Jukka Ukkonen]

Hello all,

I was trying to build kyotocabinet from the ports tree
on an old PowerMac G4 Quicksilver, but the attempt failed
in a very peculiar manner...
Do these complaints from cc ring any bells...

./libkyotocabinet.so: undefined reference to `__sync_lock_test_and_set_8'
./libkyotocabinet.so: undefined reference to `__sync_fetch_and_add_8'
./libkyotocabinet.so: undefined reference to
`__sync_bool_compare_and_swap_8'
./libkyotocabinet.so: undefined reference to `__sync_lock_test_and_set_8'
./libkyotocabinet.so: undefined reference to `__sync_fetch_and_add_8'
./libkyotocabinet.so: undefined reference to
`__sync_bool_compare_and_swap_8'

Those missing names are apparenly being referenced by
work/kyotocabinet-1.2.76/kcthread.cc. Since I failed
to find the definition of these names anywhere in the
kyotocabinet source, I assume the names are used in
some compiler header file.
Were those names really intended to be in the headers
as-is or were they actually some sort of place holders
for something which have then been completely forgotten
for some reason?

The all important details of the system are...
