ForkI'm wondering if anyone has more information or knows what the issue is
here. I am using a fresh MinGW install with GCC 9.2.0 on Windows 10.
```
C:\Users\dash\repos\link-bug>g++ --version
g++ (MinGW.org GCC Build-20200227-1) 9.2.0
Copyright (C) 2019 Free Software Foundation, Inc.

```
The following minimal example causes a linker undefined error with g++/ld.
```c++
#include <iostream>
#include <string>
using namespace std;
int main(int argc, char* argv[])
{
cout << to_string(42) << endl;
return 0;
}
```
```
C:\Users\dash\repos\link-bug>g++ main.cpp -o main
c:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe:
c:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../libmingw32.a(mbrscan.o):(.text+0xb6):

c:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe:

collect2.exe: error: ld returned 1 exit status
```
Any ideas? That should of course link without needing to specify any
additional libraries for linking. The minimal example works fine on Gnu
GCC 9.3.0 on linux and on MacOS.
