In my installation  linux is a symbolic link to arch-i386 in the same directory.

[shackle-at-wiske include]# ls -l /usr/src/rtlinux-2.0/rtl/include/linux
lrwxrwxrwx   1 root     root            9 Feb 25 13:34 
/usr/src/rtlinux-2.0/rtl/include/linux -> arch-i386
[shackle-at-wiske include]# ls -l /usr/src/rtlinux-2.0/rtl/include/arch-i386/
total 20
-rw-r--r--   1 root     root         1095 Oct 27 16:58 rt_irq.h
-rw-r--r--   1 root     root          274 Nov 13 16:58 rt_time.h
-rw-r--r--   1 root     root           36 Oct 13 00:11 rtl_fpu.h
-rw-r--r--   1 root     root         1094 Oct 21 15:33 rtl_switch.h
-rw-r--r--   1 root     root         2433 Nov 13 16:58 rtl_time.h

And in the Makefile in /usr/src/rtlinux-2.0/rtl there is a line that says
this:

ln -s arch-$(ARCH) include/linux

Did you do a "make all" in this directory?

Adding a non-existant directory to the include path is not an error in itself,
however if it can't find one of those header files above this might be the reason.

Adding a non-existant directory in the include path is not an error

Yes, we need to find someway to get the __SMP__ flags and this one set automatically
to be correct for the system were installing under any platform. We could set it to 
386 to work anywhere but that would leave most people with less than optimal 
performance.
(I'll work on it. In the meantime set this the same as you have it set for RTL and 
the kernel compiles.)

The makedepend program seemed to come with both RedHat 5.2 and RedHat 6.1 by default.
Perhaps it doesn't come with slackware, or perhaps it does but there is an option 
that needed to be chosen, or it was installed in another directory.

I have put a copy on ftp://ftp.isd.mel.nist.gov/pub/emc

My guess it has something to do with xemc which I no little about. So I'll leave this
for someone else.

Do you have the file emc/src/emcio/iosh.cc?

If not I put a copy by itself on the FTP site, although I have no idea why it wasn't 
in the distribution.

Probably either bridgeporttask or bridgeportio (both of which should have ended up
in plat/linux_2_2_13/bin) doesn't exist because of one of those compile errors.
If there both there you might check the sim.ini file to be sure the PLAT variables
are set to linux_2_2_13 and not linux_2_0_36.
