Martin Sebor updated STDCXX-408:
--------------------------------
Severity: Inefficiency
Environment: HP aCC 3.37 and beyond, gcc/Linux (was: HP aCC 3.37 and
beyond)
Summary: make use of __declspec(dll{export,import}) on all platforms
(was: [HP aCC 3.37] use __declspec(dll{export,import}))
gcc also implements the __declspec(dll{im,ex}port) feature as an alternative to
__attribute__((dll{ex,im}port):
http://gcc.gnu.org/onlinedocs/gcc-4.1.0/gcc/Function-Attributes.html
We might as well implement this enhancement across all platforms.

> Key: STDCXX-408
> URL: https://issues.apache.org/jira/browse/STDCXX-408
> 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 http://docs.hp.com/en/2212/A-03-37relnotes.html.
> We should enable this in our builds.
