The scope of a variable begins just after the completion of its
declarator.  /All/ variables in all varieties of C must be declared at
the top of their scope, since that's where their scope starts.

In C90, local variables can only be declared at the start of a block,
before any statements - but they don't have to be at the top of the
function.

That is contrary to what many others find.  Personal preferences are, of
course, personal.

There is nothing in C90 that prevents the existence and use of a header
of that name containing such typedefs.

None of these are, AFAIK, compiler extensions.  They are library
functions (and types).

The type "__int128" is a gcc extension.  (And if you have __uint128_t,
presumably it is a typedef of "unsigned __int128".)

You might find you are using other gcc extensions without thinking about
it, as a number of features of C99 started off as gcc extensions to C90.
