Known: yes.  Bug: NO.  stdout is line-buffered, so incomplete lines don't
get printed.  The reason is performance: writing to the screen requires a
switch from protected mode to real mode and back, which would 
tremendously slow down the output if you do that for each character.

Please read section 9.4 of the DJGPP FAQ.  It describes several ways to 
make that code do what you'd expect.  The FAQ is available as 
v2/faq210b.zip from the same place you get DJGPP.
