It is not just PA_RISC: these errno values are not defined on HP-UX ia64 either. They are also not defined on Tru64 and VMS and, based on comments in <boost/cerrno.hpp>, on Windows. <boost/cerrno.hpp> defines unique values for errno values missing on different systems. These (unique) values are high enough to not collide with the values in <errno.h>. I think, this is for completeness and I don't understand why you think that the missing values should not be defined at all. The author of Boost.System library will give you definitive answer.

Hi.
HP-UX PA_RISC is missing EOWNERDEAD and ENOTRECOVERABLE system error code constants required by the Boost System library. They are not critical to Boost System and are only converted to some Boost System constants as a convenience to the user. My guess is that they should not be used by Boost System unless the base OS defines them.
Tested with the Boost System library distributed with the Boost ASIO 1.38 release. [This is related to our todays posting (PA_RISC HP-UX 11.11 port) on the Boost ASIO list.]
Hope this helps.
Best regards, Jurko Gospodnetić
