Hi Boris.
The following change broke Boost.Asio library on HP-UX ia64 aCC (runner HP-UX_ia64_aCC). The library used to be green on the trunk and is still green on release branch.
It seems Christopher used the __hpux preprocessor macro to detect whether to include the fixes and that this is not enough. I guess newer HP-UX OSs have the pselect() function declared in sys/select.h which is non existant on older ones. Do you perhaps know which macros to use to make the preprocessor detect whether the program is being compiled on HP-UX PA_RISC 11.11 or some later platform that does not need these fixes? (I do not have HP-UX machines available here at the moment :-(). Many thanks for all the help with this. Best regards, Jurko Gospodnetić
