New Features in Version A.03.80
HP aC++ version A.03.80 introduces a new command line option +hpxstd98.
The +hpxstd98 command line option
The +hpxstd98 is a command line option that enables new, standard compliant compilation mode. This

versions of the compiler.

• Improved support for templates (including support for template-template parameters)
