Just for fun, I did that, and got the following.  

/bin/sh ../../libtool --mode=compile egcs -DHAVE_CONFIG_H -I. -I.
-I../.. -I./../collections -I./../defobj -I./../objectbase -I.. -I./..
-I./../gui -I./../misc -I./../activity -I./../tclobjc

-Werror -I/usr/X11R6/include -Wno-implicit-int -c -fPIC -DPIC LinkItem.m
LinkItem.m:46: macro `strdup' used with too many (6) args
LinkItem.m:51: macro `strdup' used with too many (6) args
make[4]: *** [LinkItem.lo] Error 1

I've seen this one before, and luckily Marcus had shown me how to fix
it.

This error was found in LinkItem.m (twice) once in common.m, once in a
file called OvalNode (full name?).   The trouble-causing lines all have
a format like this

    something = strdup([[globalTkInterp eval: "lots of complicated
crap"]] result]);

And the error  goes away if you rewrite it as

     id A;
      A=[globalTkInterp eval: "lots of complicated crap"]];
      something= strdup([A result]);

After that, Swarm compiled and I installed it in an out of the way
place,  /home/pauljohn/swarm-1.4.1.  

After compiling, I got an app that DID RUN but there was still a bunch
of compiler warnings like this:

But it does run, and I'm patting my own back for remembering the strdup
trick, but I'm afraid I'm out of my league on this objc_class_name_ not
defined warning.
