I did try to specify C99 as you suggested

OK, good news that that worked at least.


but I get a new error now:

/home/saspark2/build2//tmp/unpack/p4est-2.3.2/sc/src/sc_io.c(581): warning #266: function "fileno" declared implicitly
     retval = fsync (fileno (file));
                     ^

/home/saspark2/build2//tmp/unpack/p4est-2.3.2/sc/src/sc_random.c(153): error: identifier "M_PI" is undefined
         t = tan (M_PI * sc_rand (state));
                  ^

I'm afraid that you might have to edit these source files yourself. We're not the authors of p4est, so there is nothing I can fix myself, but I did open github issues for everything:
  https://github.com/cburstedde/libsc/issues/66
  https://github.com/cburstedde/libsc/issues/65
  https://github.com/cburstedde/p4est/issues/133
I *think* that it should work if you added the #include directives mentioned in these issues to the two libsc files. This may or may not be enough to get things compiled...

Best
