Failure to compile BIND 9.3.1rc1 on HP-UX

[Stefan Puiu]

I'm trying to compile BIND 9.3.1rc1 on HP-UX 11i (PA-RISC) using the aCC 
compiler version A.03.55, but the ./configure script fails with the 
following message:

configure: error: need either working unistd.h or sys/select.h

I'm not very familiar with autoconf, so I'm not sure what the solution 
would be. Any suggestions?

[stefan at hpux bind-9.3.1rc1]$ uname -s -r
HP-UX B.11.11

[stefan at hpux bind-9.3.1rc1]$ aCC -V
aCC: HP ANSI C++ B3910B A.03.55

[stefan at hpux bind-9.3.1rc1]$ model
