It does.
The stdout is buffered inside the C program, until you either print enough
data to overflow the buffer, or until you output a newline.

Borland does not care about performance, or buffering, and outputs each
character immediately.

On Linux (and probably djgpp), disable the buffering.

No it is not a bug, it is documented behaviour. If you don't read the
manual, that doesn't make the compiler buggy !!

And he is right.

So why not use Borland if that compiler is better ? We don't care.
But please don't assume that a commercial compiler is better because it
behaves more like you want.

djgpp is not a language.
as far as I know, it works for djgpp only, but if you want to know, you
should read the manual of allegro.

look at the files in www.delorie.com/pub/djgpp/v2*
That is everything which is part of the djgpp distribution.

Otherwise try a search on `library' and `djgpp' on the net :-)
