Every serious C development environment has something like this. But
note that it still restricts you to the types that C happens to have
choosen. On a system with 8,16,32 and 64 bit integers there is no way to
get an economic 24-bit integer. Check Ada for a more flexible way to
specify integers. But Ada is a much moer complex language, and has never
realy gained the momentum in the embedded world.
