C99's "{ 0 }" notation for filling in a struct with all zeros was not
included in the C++11 standard, so gcc doesn't implement it and neither
does clang.
gcc does (did?) have issues with warnings on the same code in C99,
complaining about uninitialized struct members when "{0}" explicitly
initializes every member to a zero value. These issues don't apply in
the C++ code where NTOA_TABLE_ENTRY_END is used.
