Yes, it is. It uses typeof().
But ignoring that, nye has the more useful response. :)

typeof() is clearly something acceptable in gcc's C dialect. Or have they removed their own extension without the word noticing?

The thing is, can the type returned by typeof() be modified by adding the "volatile" keyword, how much can it be modified (how to remove volatility, possible to change the sign-ness by adding signed/unsigned)...
