I realize that, but I was thinking that I could just generate a DllMain in  
D code[1], and then output it as a special case[2] as is done with regular  
D main:

For the second step though, I could also call staticctor/staticdtor or  
something.. still workin on it ;)

Yeah... Writing out assembly as byte codes like that is a little too much  
for me. I think I can get by with the above solution.

I'm still having trouble finding where functions are exported though.  
Every instance of export_symbol() seems to be check first with isExport(),  
except all symbols are exported by default on OSX.... but from where?

It seems like it could be in either out.c or machobj.c, but I still  
haven't found it.
