So where did you get the code? Libstdc++ in current GCC trunk throw

See

for patches and build scripts, most of which are merely forked from MSYS2.
I'll look at the standard. Maybe upstream libstdc++ need a fix for
"" locale.
See N4618 [locale.cons]/6:
```plaintext
explicit locale(const char* std_name);
6 Remarks: The set of valid string argument values is "C", "", and any
implementation-defined values.
