Farid Zaripov updated STDCXX-408:
---------------------------------
Fix Version/s: (was: 4.2.1)
4.3
Since the gcc 3.4.4 on Cygwin doesn't exports the template instantiations,
declared as __declspec(dllexport), and the latest for this moment gcc 4.2.3
still doesn't correctly exports the virtual function tables (I've got the
internal compiler error during linking the strstream example against stdcxx
library) I think that __declspec(dllexport/dllimport) feature is unusable on
gcc/Cygwin. Also I can't verify this feature on HP aCC because the HP testdrive
servers still has the buggy A.06.14 version.
So I deferring this issue to the later time.
> make use of __declspec(dll{export,import}) on all platforms

> Project: C++ Standard Library
> Issue Type: Improvement
> Components: Build
> Affects Versions: 4.1.2, 4.1.3, 4.1.4, 4.2.0
> Environment: HP aCC 3.37 and beyond, gcc/Linux

>
> 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.
