<unistd.h> here in this part of the file, but that might
conflict with various other #defines and includes above, such as
#define vfork fork above.
Further, the lockf() constants aren't POSIX, so they might not be
visible if we're compiling with _POSIX_SOURCE defined. Thus, we'll
just stick in the SVID values and be done with it. Sigh.
