I don't think you should have to write that! This will teach me to test 
things more thouroughly: after I changed the type to unsigned, I forgot 
to make sure it worked in C++ (there's no problem with the type difference 
in C).

There's an easy fix, though. In allegro.h, just after the definition of 
destroy_font() (line 918), insert the lines:

<-- snip -->


#ifdef __cplusplus

}  /* end of extern "C" */


__INLINE__ void textout(BITMAP *bmp, FONT *f, char *str, int x, int y, int color)
{
   textout(bmp, f, (unsigned char *)str, x, y, color);
}


__INLINE__ void textout_centre(BITMAP *bmp, FONT *f, char *str, int x, int y, int color)
{
   textout_centre(bmp, f, (unsigned char *)str, x, y, color);
}


__INLINE__ int text_length(FONT *f, char *str)
{
   return text_length(f, (unsigned char *)str);
}


extern "C" {

#endif   /* ifdef __cplusplus */


<-- snip -->

I can't think of any problems that thich could cause. I'll upload a 
patched 2.2 tomorrow...
