OK: what you're aiming for, depends of course on a long chain of details
being all exactly correct. So let's assume for now that all has been
done correctly thus far: and deal with the gcc error 'at face value'.

Is this an issue where 'decimal128.h' does exist, but is just not
being found. Do you have a 'decimal128.h' file anywhere under your
compile/target areas - just do 'find -P / -iname decimal128.h -ls'
to get them all.


If it does exist, then it may be worth trying - at least, as a debugging
step - a symlink to it from where gcc is looking for it.
