egcs-19990830 gets the error below under sco odt 2.0 (sco unix 3.2v4.0).

My system has the sco odt 2.0 dev sys.
I am doing the build with gcc-,
gas-2.9.1 (which I have in /usr/local/bin/as, and /usr/local/bin is before
/bin in my PATH), sco /bin/ld, flex-2.5.4, bison-1.27, gmake-3.77,
and a hacked bash-2.04-alpha1.

I get the same error with gcc-2.95.1, even when I change the build to
compile with -O0.  Is there any place I should start looking?
Do I need to submit a log with --save-temps?

I have simplified the and gcc/ to reduce the command
line length with changes like the one below.

-  if [ -f $(objdir)/../binutils/ar ] ; then \
-    echo $(objdir)/../binutils/ar ; \
-  else \
-    if [ "$(host_canonical)" = "$(target)" ] ; then \
-      echo ar; \
-    else \
-       t='$(program_transform_name)'; echo ar | sed -e $$t ; \
-    fi; \
-  fi`

Here is the end of the make:
