Doesn't this add the flag to past POSIX versions?

I'd prefer if there was a test case for the new functionality, perhaps 
using the getsid function.

I wonder if we should add a new symbol version for 
posix_spawnattr_setflags, so that applications which do not perform 
error checking for the function call fail in a predictable manner.

Thanks,
Florian
