Conceptually, there is a difference, but only to yourself and other humans that read the code, the compiler doesn't care.

Some compilers are very strict about casting, in which case it would matter. On the assumption that gcc is the only compiler you will ever use, it won't matter, but that's a poor assumption long term.

I've heard that MetroWerks' compiler, for example, is more pedantic than gcc, though I'm not sure if they would be in this case.
