The compiler in question here is GCC. The existing IF statement already
specified -lpthread for the Solaris compiler. It was specifying -pthread
for GCC, which was incorrect - GCC says it is an unrecognized option.
Surely GCC on AIX isn't going to have the -pthread option, is it? Don't
know - I've never run GCC on AIX...
I think the remaining outstanding question for Solaris is -D_THREAD_SAFE.
Based on your research, -D_REENTRANT is needed for errno to be defined
properly, so it was added. But, -D_THREAD_SAFE is still not specified. Is
it needed or not needed?
