I did have to install m4 and have /usr/local/bin before /usr/bin and /bin 
so it uses the gnu m4.

I have m4-1.4.3 at 

ftp://ftp.zenez.com/pub/zenez/prgms/m4-1.4.3-osr6-all.tar.gz

I really have to be able to use configure for most of my OpenSource 
Projects for SCO OS's.

I made the changes so that most things work with the auto tools.

I did a VM install of OpenServer 6 to try things out.  I was able to get 
your -Wall failure, but once I ran the CC=cc CXX=CC ./configure I was able 
to run gmake without any errors. I did have to install the M4 from above 
to get configure to work.  So, the straight out of the box install has to 
have gnu m4 to run configure.

-g and -O2 are mutually exclusive.  You can have either one but not both.

I do have tcl and tk

drwxr-xr-x   12 gerberb  zenez       2048 Jun 10 17:30 tcl8.5.2
drwxr-xr-x   12 gerberb  zenez       2048 Jun 10 17:30 tk8.5.2

So I am not sure what the best option should be.  There is a patch for 
UnixWare 7 MP4 that has to be installed to MP4 for so failures, but it 
works even with ksh with it.

Also on UnixWare 7.1.4 I could not get any m4 greater than 1.4.9 to 
compile and work.  I finally just used 

drwxr-xr-x    8 gerberb  zenez          2048 May 19 03:05 m4-1.4.9
drwxrwxrwx    9 gerberb  zenez          4096 Apr  3 00:11 make-3.81
drwxr-xr-x   12 gerberb  zenez          2048 Jun 10 16:43 tcl8.5.2
drwxr-xr-x   12 gerberb  zenez          2048 Jun 10 16:44 tk8.5.2
drwxr-xr-x    9 gerberb  zenez          4096 May 19 03:18 sed-4.1.4

On UnixWare 7.1.4 MP4 with ptf9055a.
