The above message contained the following:

Odd. According to the output of the configure script, your development
environment supplies everything that's needed -- so the C header files
"stddef.h", "stdlib.h", and "time.h" should not have been created in the
"port/misc" subdirectory and the file "atexit.o" should not have been
added to the LIBOBJS macro in the makefile "port/misc/Makefile". I do
not understand how this puzzling behavior could have occurred.

As a workaround, please try the following:

    1.  Go to the "port/misc" subdirectory.

    2.  Remove the files "stddef.h", "stdlib.h", and "time.h".

    3.  Edit the file Makefile: remove the name "atexit.o" from the
        macro LIBOBJS.

    4.  Go to the top-level source directory.

    5.  Execute the command "make clean".

    6.  Perform steps 6 through 9 described near the end of the INSTALL
        file.

Please let me know if this helps.
