That may prove difficult, since Darwin is not considered a prime target of GCC these days.

How can I resolve this?
Do you have any environment variables whose names begin with DYLD (check by
typing env), or do you have anything installed in /usr/local? These things
can interfere.
Just checked = No
If that's not it, you may need to ask the developers of gcc.
Of course I could not attempt to replicate the problem on my system because:
$ gcc-mp-4.6 -std=gnu++0x AutoTest.cc
gcc-mp-4.6: error: AutoTest.cc: No such file or directory
gcc-mp-4.6: fatal error: no input files
compilation terminated.
If you'd like us to try, supply the source file you used.
Here are the file's contents:
#include iostream
int main() {
auto i = 5;
std::cout i std::endl;
}

I get the same as you. So either this is not how GCC is meant to be used (ask
