Martin Sebor updated STDCXX-408:
--------------------------------

    Fix Version/s: 4.2.1

This should be pretty straightforward assuming the feature works the same way in aCC as in MSVC and assuming there are no serious bugs in it. Yeah, right. Scheduled 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 http://docs.hp.com/en/2212/A-03-37relnotes.html.
> We should enable this in our builds.
