GLib seems to have taken the alternative approach you suggested and uses 
wrappers around the stdio functions - g_fopen() instead of fopen(), etc. 
  Their implementation uses the "wide character" API on NT-based 
Windows systems and the "8-bit character in current locale" API on 
DOS-based Windows systems.  It looks like Tor Lillqvist is mostly 
responsible for this implementation.
