macroNL0

These manifest constants have the same names as those in the header <sys/ioctl_compat.h>, so you are not permitted to have both definitions in scope simultaneously in the same compilation unit. Nevertheless, they are required to be in scope when _POSIX_C_SOURCE is requested; this means that including the <sys/ioctl_compat.h> header before this one when _POSIX_C_SOURCE is in scope will result in redefintions. We attempt to maintain these as the same values so as to avoid this being an outright error in most compilers.
