Is it export surface (dllimport/dllexport) issue? It feels like static symbols broke for .lib on MinGW.

Is it export surface (dllimport/dllexport) issue? It feels like static symbols broke for .lib on MinGW.

I've also find a similar issue on MinGW: jbaldwin/libcoro#283
We need to investigate the different effects of these function decoration:

• __attribute__((visibility("default")))
• __declspec((dllexport/dllimport))
• __attribute__((dllexport/dllimport))

I tried to rely over existing implementation, it required to add two more syslinks. It seems passing.
