[jira] [Commented] (DISPATCH-2272) Mark all functions called from

> Please raise a discussion on the qpid-dispatch apache mailing list regarding win32 support. Adding win32 support is a big deal and needs to be discussed at the project level.
It has been discussed multiple times, see the "Previous discussions" section on https://issues.apache.org/jira/browse/DISPATCH-2027. Why do you think there is something more to say than what was already mentioned?
Actually, from my experience, it is not such a big deal. It greatly depends on what do you mean by "Windows support". What @ppatierno did in the tweet linked in Jira (running Dispatch in Windows Subsystem for Linux) was AFAIK quite simple user-level effort, which nevertheless got you there. My goal is to be able to build a native Windows binary in Visual Studio, but using the Clang compiler (VS offers a choice of MSVC and Clang on Windows; Clang obviously requires less effort). That is somewhat bigger deal, but nothing too crazy.
@kgiusti Do I need to create a new thread, or can I reuse one of the existing ones?

> Dispatch requires that all C functions it calls be exported, because it looks them up as if in a dynamic library. This is important on Windows, where functions are unexported by default.
> On Windows, use {{__declspec(dllexport)}} to turn on exporting. Without it, the functions will not be found from Python.
