It appears that conftest is used abundantly in the configure script, but 
only shows up at only one or two spots in the unprocessed source tree. 
That is, running either "bootstrap" or "configure" expands this command. 
 So you might have to go back to a clean source tree and run 
"bootstrap" so see if there is a bad path for the gcc library.

One other thing that might be a lead is that in the instructions of 
INSTALL.OCTAVE is the note:

     *You should not change the files in `/usr/include'*.  You can find
     the `gcc' include directory tree by running the command

          gcc -print-libgcc-file-name

     The directory of `gcc' include files normally begins in the same
     directory that contains the file `libgcc.a'.

Try that command and see if it agrees or not with one of the paths 
you've listed.
