IMHO calling conventions ( like _stdcall and _cdecl ) are about 
parameter cleanup and ordering and exnrnal c linkage is about how the 
function name is written ( mangled or not). I can see that calling 
convention could make problems with pthread, but cannot see what extern 
"C" should have to to with that.
please enligthen me.
