Yep, that looks broken.
$ cat tsleeptest.c

#include <sys/proc.h>
int main() { return 0; }
$ cc -o tsleeptest tsleeptest.c
In file included from tsleeptest.c:2:

The macros for 'major' and 'minor' are being substituted in for these
major() and minor() functions. You might want to try sending in a PR,
see send-pr(1). The documentation on the manpage saying to use these
h-files might be the problem too.
