It appears to me that HP intentionally declares 'errno' with both
'C' and 'C++' linkage. This is what I see in sys/errno.h:
# ifdef __cplusplus
extern "C" {
# endif /* __cplusplus */
# if defined(_REENTRANT) && !defined(_PTHREADS_DRAFT4)
/* Get errno definition by including <errno.h> not <sys/errno.h> */
# else /* ! _REENTRANT || _PTHREADS_DRAFT4 */
extern int errno;
# endif /* ! _REENTRANT || _PTHREADS_DRAFT4 */
# ifdef __cplusplus
}
# endif /* __cplusplus */
