Not so. Declarations with initialisations have always been legal at the
beginning of a block.

C99 also permits declarations to follow statements, like C++.

C90 vs C99

In C90 the initializations must be literals: you can't put an arbitrary
function call in there and expect it to work. (That's a GNU C extension,
copied from C++ and also found in C99: look up `Non-Constant Initializers'
in the manual.)
