Jozef was right, and you were iron right, just straight to the middle.
So I decided to listen to your advice, and to build aside VBox VM
environment. I have chosen Fedora 23 server, built the VBox VM with
Fedora 23, and the initial issue disappeared.

But another issue appeared. It is somehow described very well here,
and many people at the same time had this problem:
https://lists.yoctoproject.org/pipermail/yocto/2015-February/023624.html

I then continued to search, and found the following:
https://stackoverflow.com/questions/37475222/ncurses-6-0-compilation-error-error-expected-before-int

I did this: export CPPFLAGS="-P", but this did not help. Then I
advanced gcc to F25 package (6.4.1), it did not help either. Advancing
to Fedora 26 (7.3) revamped/resurfaced the original problem, so I did
regress gcc back to Fedora 24 version (6.3.1).

What could be the problem here?

Thank you,
Zoran
