Martin Sebor commented on STDCXX-743:
-------------------------------------
HP says "??this works fine with A.03.80 with the option
[+hpxstd98|http://docs.hp.com/en/11920/HP%20aC++%20Online%20Programmer's%20Guide/options.htm#opt+hpxstd98].??"
I've confirmed that aCC 3.77 also accepts the option and successfully compiles
the code.
We might want to consider using the option.
