What you could do to fix them is to move the functions implemented in
trace.h to an src/skins/common/trace.c, this would allow to remove
asm/xenomai/syscall.h from nucleus/trace.h, and would solve most of the
warnings you are showing us. When you are done and it works for you,
please submit a patch.

As for the variadic macros, I believe they exist in C99, so perhaps you
are not compiling with the right flag, or perhaps we do not use the C99
syntax, which probably could be fixed too.
