   I couldn't get my INT64_T to work, and I suspect I need to install   
   more packages in my mingw64 thingy. Adding the header files made no difference.   
      
   /* #include  */   
   /* #include  */   
   #include    
      
   /* gcc      -std=c99 -o wide.exe wide.c */   
   /* gcc -m64 -std=c99 -o wide.exe wide.c */   
      
   int main( void )   
   {   
      wchar_t buf[100];   
      /* int64_t i; */   
      long long int i;   
      
      i = 5000000000000 ;   
      
      int len = swprintf( buf, 100, L"%s %+lld %s", L"Pack my box with ", i, L"   
   liquor jugs" );   
      printf( "Generated %d characters\n\n", len );   
      
      wprintf(L"%ls\n\n", buf);   
   }   
      
    UCRT64 ~   
   $ ./wide   
   Generated 45 characters   
      
   Pack my box with  +5000000000000  liquor jugs
