I just tried this, and it isn't giving me a warning for an
uninitialized variable when I do a syntax check. This warning requires
compiling with -O (or some other -O setting.
I have to set the active build style to deployment (to enable compiling
with optimization) and then Build instead of Check Syntax to see this
warning.
Since I work on multiple platforms and compilers, the habit of
initializing variables serves me well when the compiler doesn't have
the option for this kind of warning.
