It is better to have only the option to sign one selected user ID
instead of all user IDs together.  You are often not able to sign
all user IDs.

Ah, not again this thread.  Using memset to zero out a structure is
okay.  There are only a very few strange systems where the NULL
pointer is not represented by all zero bits and the compiler has to
translate each pointer assignment which is not possibly if you just
zero out the memory.

If someone wants to have this software run on such a strange system,
he has to port it (which actually is quite easy) or pay someone to
do it.  Adding separate initializing for dynamically allocated stuff
is very prone to errors.

Some compilers on really used systems even complain about
incomplete initializings like:

struct foo bar = {0,};
