So I fixed all compiler generated warnigns except these:

[midas@pc2075 ~/elog]$ gcc -g -O -W -Wall -o elogd src/elogd.c
src/elogd.c: In function `set_cookie':
src/elogd.c:4675: warning: `%y' yields only last 2 digits of year
src/elogd.c: In function `send_file_direct':
src/elogd.c:5483: warning: `%y' yields only last 2 digits of year
src/elogd.c: In function `show_elog_list':

src/elogd.c:11957: warning: `%x' yields only last 2 digits of year in some

src/elogd.c:11987: warning: `%x' yields only last 2 digits of year in some

src/elogd.c: In function `ctrlc_handler':
src/elogd.c:15864: warning: empty body in an if-statement
src/elogd.c: In function `hup_handler':
src/elogd.c:15870: warning: empty body in an if-statement

Do you know how to disable these warnings or any other workaround? I would 
like to compile without any remaining warnings.
