strupr is not a standard C library function.

What to do

Write it yourself, huh.
It is not difficult to process only English ASCII characters.

char * strupr (char * str)
{
   char * ptr = str;

   while (* ptr! = '\0') {
       if (islower (* ptr))
            * ptr = toupper (* ptr);
       ptr ++;
   }

   return str;
}
