[PD-dev] Problem building pdlua on MinGW (solved for now)

[PSPunch]

I think lua_setup() needs to be 'exported' in order to be read 
externally with Windows DLLs.
So, if the only route to have m_pd.h define the EXTERN macro as 
expected, what will be a clean way to add __declspec(dllexport) to the 
function definition and yet let the code remain compatible with other 
platforms?
Simply introduce new macros in lua.c?


Also, from your description I thought that PD_INTERNAL was reserved for 
internal functions or classes, etc. However, when grepping the source of 
vanilla Pd,  I did not find the macro being used anywhere else other 
than this part of m_pd.h.
What is this reserved for?
