Hi leif, thank you for looking into this issue as well.
Attached is my cf_gmp.h after a failed build attempt with sage -f
singular-3-1-5.p7
Well, that version doesn't include bits/c++config.h. (It doesn't have
as many lines as the previous one where the error occurred, and at first
glance looks pretty sane.)
Do you get a different error now?

The problem is not that a C compiler is used to compile weight0.c, but
that cf_gmp.h includes <bits/c++config.h> in the first place.
(Although bits/c++config.h is valid C code as well, it's not in the
[C++] include path if you compile a file as C code which includes it.)
But it seems ArchLinux's broken gcc/g++ behaviour triggers the problem.
Pong, could you upload/attach your cf_gmp.h? (Should be located in
$SAGE_ROOT/spkg/build/singular-3-1-5.p7/src/factory/, but only after a
failed build or if you use 'sage -f -s ...', or alternatively set
SAGE_KEEP_BUILT_SPKGS=yes.)
I'll take a look at the full Singular build log you attached earlier.
