Hello Samuel,

Is what we usually use. In principle Cactus does support both
traditional and modern CPP. Just not every single thorn that uses
Cactus but is not in a Cactus* repository (so most Cactus thorn will
compile, though I would not want to bet on whether the CCTK_LOOP
macros will work with modern CPP).

Well it's technically a bug (violation of using the CCTK_FNAME API as
doucmented) in SummationByParts.

I recently fixed a similar issue in loopcontrol. I will give
SummationByParts the similar treatment if I can.

Yours,
Roland
