double-underscore ones, except __NFDBITS, __FD_SETSIZE and
__FDSET_LONGS which are defined in <linux/posix_types.h>.
Unfortunately, some architectures define the double-underscore ones
as inlines, so we can't use a simple #ifdef test. Thus, the only
safe option remaining is to #undef the top-level macros. */
