with my head and bare hands. well, armed with some regular 
expressions. did you seen some of my "port" announcements? they 
all done manually. it's not that hard, mostly search-and-replace.

also, i did used c++ 'cause it has `auto` feature, so i pasted 
your declaration, and then played with c++ and -Wall until it 
silenced. actually,

void zoo (void) {}
auto goo (sqlite3_vfs *a,void *b, const char *zSymbol) { return 
&zoo; }

was taken verbatim from c++. as you can see, it even has 
`(void)`, which is forbidden in D (but allowed in my dmd fork ;-).
