also the simple example on
https://en.cppreference.com/w/cpp/locale/locale


$ cat test-locale.cpp
#include <iostream>
#include <locale>

int main()
{
     std::wcout << "User-preferred locale setting is " << 
std::locale("").name().c_str() << '\n';
     // on startup, the global locale is the "C" locale
     std::wcout << 1000.01 << '\n';
     // replace the C++ global locale as well as the C locale with the 
user-preferred locale
     std::locale::global(std::locale(""));
     // use the new global locale for future wide character output
     std::wcout.imbue(std::locale());
     // output the same number again
     std::wcout << 1000.01 << '\n';
}


  ./test-locale.exe
terminate called after throwing an instance of 'std::runtime_error'
   what():  locale::facet::_S_create_c_locale name not valid
Aborted (core dumped)


so or the standard is changed or Cygwin implementation has an issue
