The problem is that I have bad experiences when using different compilers
... While I admit you're right about this topic, I would never use a
variable which is not initalized before. Just because it's more readable and
portable. Portable in that way that 'real compilers' don't always follow
standard unfortunately, and it's worth to be extra careful when using
different - even exotic - compilers ...
