Yes, please. And also include feature testing macros. That will make
the life of authors of kernel-dependent but portable software much
easier.
I.e. if you add something like
struct my_foo_ioctl { int stuff; };
also add
#define HAVE_MY_FOO_IOCTL 1

(If absolutely necessary and indispensable, a definition may also be
deleted along with its feature macro, but this should not become the
norm.)
