decltype can be useful, but is not available when compiling with gcc 4.4.

typeof sounds very similar:

"A `typeof'-construct can be used anywhere a typedef name could be
used.  For example, you can use it in a declaration, in a cast, or
inside of `sizeof' or `typeof'."

"If you are writing a header file that must work when included in ISO C
programs, write `__typeof__' instead of `typeof'."

If bug 810274 comment 18 is correct that we might be able to reconsider decltype in Firefox 25, this is gonna have a short lifetime, but that's probably not a bad thing.
