Hi Xi.
Hi Michael, Paul and Ken.
Thank you all for your comments suggestions and tips.
Firstly, I have adjusted my Gmail. Please tell me if I am still
top-posting. It is a new term to me but I did find Gmail confusing.
Xi, I restarted from Chapter 6 with my saved /tools directory.
I also did "Adjusting the Toolchain" after 6.16.
While running the 'make' step in 6.18.1 I noticed a number of warnings
similar to:
"In file included from mpfr-impl.h:108:0,
from beta.c:24:
mpfr.h:432:51: warning: ISO C does not support decimal floating point
[-Wpedantic]
__MPFR_DECLSPEC int mpfr_set_decimal64 (mpfr_ptr, _Decimal64, mpfr_rnd_t);
^~~~~~~~~~
mpfr.h:483:17: warning: ISO C does not support decimal floating point
[-Wpedantic]
__MPFR_DECLSPEC _Decimal64 mpfr_get_decimal64 (mpfr_srcptr, mpfr_rnd_t);"
I assumed an error was coming.
However the make check passed 100%
I'm afraid I do not have a copy of yesterday's steps as I issued a stupid
command and closed the host down.
Sorry.
I do have a copy of today's bash history( :)) but of course that helps
no-one.

Thank you Ken especially for the 'history >/duff-hist' tip. Hope I remember
that.
Thanks everyone once again.
I am proceeding.
