Probably not:
HP-UX 10.20, 11.00, 11.11, 11.23/PA, and 11.23/IPF all have:

/usr/include 103 > grep -r POSIX_VERSION * sys/unistd.h:# define _POSIX_VERSION _POSIX1_VERSION_88 sys/unistd.h:# define _POSIX_VERSION _POSIX1_VERSION_90 sys/unistd.h:# define _POSIX_VERSION _POSIX1_VERSION_93 sys/unistd.h:# define _SC_1_VERSION_88 7 /* _POSIX_VERSION: Date of POSIX.1-1988 */ sys/unistd.h:# define _SC_1_VERSION_90 102 /* _POSIX_VERSION: Date of POSIX.1-1990 */ sys/unistd.h:# define _SC_1_VERSION_93 103 /* _POSIX_VERSION: Date of POSIX.1b-1993 */ sys/unistd.h:# if (_POSIX_VERSION == _POSIX1_VERSION_88) sys/unistd.h:# if (_POSIX_VERSION == _POSIX1_VERSION_90)

and the two 11.23 do have select.h
