The only way I know of (short of replacing DOS I/O with conio) is to use
the filesystem extensions mechanism available with DJGPP v2.  A simple
example of a filesystem extension which catches all output to the screen
(no matter which higher-level I/O functions were used) and converts it to
direct conio-style writes is included with the DJGPP libc reference from
v2.01 (type "info libc alpha __FSEXT_set_function RET" from the DOS
prompt).  A more complex example can be found in the DJGPP port of GNU ls
(v2gnu/fil313s.zip, filename ls-msdos.c) which is used to produce the
colorization of file names according to their type.
