A poor man's ANSI driver can be found in the DJGPP port of GNU Fileutils
(v2gnu/fil313b.zip, file src/ls-msdos.c).  It only handles the color
commands of ANSI command set, and it assumes that the text doesn't include
TAB characters, but you can extend it if it isn't enough.  The driver
works by installing a filesystem extension for console output, so that it
is automatically called by the low-level I/O functions when the program
prints to the screen.  (I needed it to make ls colorize its output.)
