If you are running IRIX 5.xx, (or IRIX 6.2 )you will need to modify all the
Makefiles so that the compile flags include contain the definition 
for the OLD_TERMIOS structure:

CFLAGS= -c -g -D_OLD_TERMIOS $(XFLAGS) -fullwarn

This will makes sure that the set_baud function uses the old termios data
structure.
