how to ignore "X variable may be used uninitialized in this function"


Hi,

I got this "cond" may be used uninitialized in this function waring in
compiling my program.

I used -Wuninitialized to ignore this warning, but it does not work.
Do you know which option (-W????) is for this  "X variable may be used
uninitialized in this function"? Thanks

Regards,
Joe
