We could have a different implementation for initializing those function pointers for different platforms or we could have OSX and Linux both share the same implementation. What would you prefer?


I expect dlsym to work equally well on linux, so, yes, let's make it the same on both. 
+1 to struct of function pointers. Declare it in a separate header file, initialize it in a separate .cpp file. 
FuzzerDlsym.cpp?  FuzzerWeakSymbols.cpp? [naming is hard]
