Here's the macro definition you cited upthread:
"""
From /usr/include/«arch»/bits/select.h on my Debian system:

    #define __FD_ZERO(s) \
      do {                                                                            \
        unsigned int __i;                                                             \
        fd_set *__arr = (s);                                                  \
        for (__i = 0; __i < sizeof (fd_set) / sizeof (__fd_mask); ++__i)              \
          __FDS_BITS (__arr)[__i] = 0;                                        \
      } while (0)
"""

Can you explain how that would cause a problem?

Note the following that precedes the macro definition in
/usr/include/x86_64-linux-gnu/bits/select.h on my Ubuntu system:

"""
#ifndef _SYS_SELECT_H
# error "Never use <bits/select.h> directly; include <sys/select.h> instead."
#endif
"""

so it's not going to be invoked from user-written code.
