   Attached... perhaps it will also help you to know that I'm also unable
   to get through tests of diffutils-3.2 with my gcc, although HP's
   compiler manages it.  Perhaps some gcc's are less-than-perfect here.

Thanks.  I notice that all of the tests fail with a message from
/usr/local/bin/gdiff3, yet config.log indicates that gdiff3 is not
"sane enough" (i.e., ‘DIFF3_BIN’ is set to value ‘0’).  That's
peculiar.

I think we need to focus on the configure script failing to recognize
that /usr/local/bin/gdiff3 is actually GNU diff3.  Could you apply
the attached patch, rerun the configure script (delete config.cache
first to be safe), and post the contents of the two generated files
SAVE.out and SAVE.err?

Related to this line of debugging, could you also try to add
  #undef DIFF3_BIN
  #define DIFF3_BIN 1
to src/merger.c (anywhere prior to func ‘merge’ is fine), and
redo "make && make check"?  (Any change in luck?)

BTW, have you reported the diffutils problems to the diffutils folks?

   Should I be able to compile with a non-gcc c89?

No, RCS requires a c99 compiler.  The configure script should exit
failurefully if it cannot find or finangle one.
