>                 Key: STDCXX-408
>                 URL:
>             Project: C++ Standard Library
>          Issue Type: Improvement
>          Components: Build
>    Affects Versions: 4.1.3
>         Environment: HP aCC 3.37 and beyond, gcc/Linux
>            Reporter: Martin Sebor
>             Fix For: 4.2.1
> Starting with HP aCC 3.37 the compiler supports the __declspec(dllexport) and __declspec(dllimport)
decorators on declarations of symbols with external linkage. According to the Release Notes
for the compiler, "Support of these keywords enhances the performance of shared libraries
and relieves the usage of HP_DEFINED_EXTERNAL pragmas and +Oextern= list to hide the non-exported
symbols." See
> We should enable this in our builds.
