configure goes endless executing the following statements:
quote
-----------------
  # If we had to re-execute with $CONFIG_SHELL, we're ensured to have
  # already done that, so ensure we don't try to do so again and fall
  # in an infinite loop.  This has already happened in practice.
  ## _as_can_reexec=no; export _as_can_reexec
  # Don't try to exec as it changes $[0], causing all sort of problems
  # (the dirname of $[0] is not the place where we might find the
  # original and so on.  Autoconf is especially sensitive to this).
  ## . "./$as_me.lineno"
  # Exit status is that of the last command.
  ## exit
}
-----------------
unquote
I commented out the  "##" statements. After that, configure worked.

However, the configuration of gmp-6.1.0 failed with a statement
" configure: error: could not find a working compiler, see config.log for 
details"

I include the full result of the configuration ( "configure-result" ) as well 
as the "config.log". May be you can analyse in some way what is happening

Again, thank you very much,
Edgar

configure: error: could not find a working compiler, see config.log for details

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by GNU MP configure 6.1.0, which was
generated by GNU Autoconf 2.69.  Invocation command line was
