GRRR!!! I *HATE* ANSI-C prototypes!!! They give programmers far far
too much rope, and we often wrap this rope very firmly around our necks!

Here's the fix to STk 2.2 for the weird failure when loading any STklos
stuff:

ttyp7:<woods_at_most> $ cvs diff Src/list.c
Index: Src/list.c
===================================================================
RCS file: /local/src-CVS/misc/STk/Src/list.c,v
retrieving revision 1.1.1.1
diff -r1.1.1.1 list.c
144c174
< if (len >= 0) return STk_makeinteger((double) len);

The one damn bug that would instantly break even an mc68k machine!
Long live lint(1)!  Hip Hip Hurray!
BTW, I'll now start checking in my changes to allow STk to compile on
non-ANSI platforms, and should be able to provide a patch soon.
Note though that I'm not going to lint the code just yet -- a quick look
at just the calls to STk_makeinteger() show there are many, many, many
function parameter casts necessary.  Luckily it's unlikely anyone will
need to run this code on a 16-bit machine, and all the 64-bit machines I
know have ANSI-C compilers natively.
Also, for whatever GCC version failed to compile this correctly (I'm
certain the prototype was in scope!) has a *VERY* serious bug -- don't
use it!!!!
