mvcrt.ungetc and stdio buffering

[Waldek Hebisch]

Recently I tried to run g77 compiled Fortran program under Wine. 
It seems that to do any input g77 uses `ungetc'. Currently, 
Wine msvcrt has unbufferd stdio. I would like to add buffering 
and implement `ungetc'. Are there any traps (thread safety ??) 
or will strightforward implementation work ?
