So with USE_ATOMICS_GENERIC I have this:
solaris.o:

[Index] Value Size Type Bind Other Shndx Name

mutex.o:

builtins.o:

-bash-3.2# for i in solaris.o mutex.o builtins.o ; do nm -u $i; done

Undefined symbols from solaris.o:

With the default build I have this:
Undefined symbols from solaris.o:

Undefined symbols from mutex.o:

Undefined symbols from builtins.o:

bash-3.2# for i in solaris.o mutex.o builtins.o ; do nm -g $i; done

solaris.o:

mutex.o:

builtins.o:

So I don't see any __sync symbols anywhere..

Does this mean they're in another dependency somewhere?
