It seems Clang doesn't like the definition of the builtin, as followed. 
File 1.cpp:

int __builtin_eh_return_data_regno(int i)
{
  return 0;
}

int main()
{
   return 0;
}


gcc compile, success:
$g++ -c 1.cpp -o test.o

clang compile, Failure:
clang++ -c 1.cpp -fno-builtin -o test.o
1.cpp:1:5: error: definition of builtin function
'__builtin_eh_return_data_regno'
int __builtin_eh_return_data_regno(int i)
    ^
1 error generated.
