Actually, I would concentrate on _TS_ERRNO (thread-safe errno, that is?) Strikes me as the most minimal and safe change, we could simply add the define to config/os/solaris/solaris2.7/os_defines.h. Can you try this change? Then, if everything goes well, we have to find out something similar for the other problematic targets...
