We actually test this platform (ubuntu xenial), and gfan builds correctly. See https://github.com/sagemath/sage/runs/3392764418?check_suite_focus=true This failure must be caused by something specific to your system - such as some stuff installed into /usr/local or something like that.

What could be the cause? I'm not sure whether I added any stuff since the last successful build. In particular, the error message I'm getting looks to me like there is something wrong in the sources (namely: A different number of arguments in the header and in the code) -- is gfan partially taken from the system?

I'd start by un-installing system-wide gfan (could it be that you have more system-wide copies of it, e.g. in /usr/local/ ?) and try building then.

I tried to "find /usr/local/ -name *gfan*", which resulted in nothing. Then I tried "sudo apt remove gfan", which told me that gfan is not installed! So, I misinterpreted "apt show gfan" (it gave me the apparently wrong impression that I had it installed. So, what next? How can I find out whether (and where) gfan is installed system-wide?

Singular vendors a part of gfan called gfanlib. Perhaps an installation of that is leaking into your build. If you can share your top-level config.log and the full gfan build log, we can take a closer look.

./configure correctly determines that it needs to use CXX='g++ -std=gnu++11' to work with this old compiler. Check if you have environment variables CC or CXX set in your global environment -- they should be unset; otherwise, they will override the values determined by ./configure. (This is nonstandard behavior of our build system.)

I will not work with my old laptop much longer and I suppose that on the new laptop (with a more recent Ubuntu) the problem will not occur. Anyway, I wanted to try if/how it is possible to solve the problem on the old laptop. For the record: "make distclean", "./configure --with-system-gcc=no" and "make build" worked. I don't know if "make distclean" directly followed by "make build" would have worked, too.

As far as I am concerned, Ubuntu 16.04 is past its EOL. We should not support it, and it will save us time messing around with obsolete compilers too (the last release in gcc 5 branch was 4 years ago, and gcc does not support anything older than gcc 9 now).

you can install g++7 package on Ubuntu 16.04. (google for instructions). This should do the trick (after distclean).
