Ah, yes, I forgot. You are right, you either need to pass a define that 
you are built static or else have it defined or not in a generated header.

Is it just the MYPROJECT_STATIC that you need to pass as a define? That 
would indeed be a good candidate for t_c_d(PUBLIC). (I got the - 
erroneous? - impression you were actually passing e.g. 
-DMY_ABI=__dllspec(dllimport)...)
