_iob is the array of FILE structs that Borland's stdio allocates from.
_iob[0] thru _iob[2] represent stdin, stdout, & stderr.

But, DJGPP uses specific FILE structs for those, namely __dj_stdin, ...etc.
Solution... I dunno. I guess you could do:
FILE *_iob[3] = { stdin, stdout, stderr };
but that's kinda yuckers.
