This adds the use of TIOCM_MODEM_BITS to irtty.c but not the corresponding
addition of it to asm-i386/termios.h:

<-- snip -->

gcc -D__KERNEL__ -I/home/bunk/linux/kernel-2.4/linux-2.4.19-full/include
-Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing
-fno-common -pipe -mpreferred-stack-boundary=2 -march=k6 -nostdinc
-iwithprefix include -DKBUILD_BASENAME=irtty -c -o irtty.o irtty.c
irtty.c: In function `irtty_set_dtr_rts':
irtty.c:761: `TIOCM_MODEM_BITS' undeclared (first use in this function)
irtty.c:761: (Each undeclared identifier is reported only once
irtty.c:761: for each function it appears in.)
make[4]: *** [irtty.o] Error 1
make[4]: Leaving directory `/home/bunk/linux/kernel-2.4/linux-2.4.19-full/drivers/net/irda'

<-- snip -->

The following part of -ac is also needed:
