Compiles C programs in 64-bit mode. Use this option
for compatibility with future architectures.
- +DA2.0W

If you are building 64-bit applications on HP-UX 11.0 32-bit
systems, be sure to request and verify that 64-bit versions of system
libraries are installed. For example, verify that /usr/lib/pa20_64/libc.sl
is installed.
64-bit applications only run on 64-bit systems.
64-bit main programs and object files can only link with 64-bit
object files and 64-bit versions of shared or archive libraries.
