Huh? 6.7.5.2p4: If the size is not present, the array type is an incomplete type. If the size is * instead of being an expression, the array type is a variable length array type of unspecified size, which can only be used in declarations with function prototype scope [footnote]; such arrays are nonetheless complete types. If the size is an integer constant expression and the element type has a known constant size, the array type is not a variable length array type; otherwise, the array type is a variable length array type. footnote: Thus, * can be used only in function declarations that are not definitions (see 6.7.5.3). That's C99, straight from N1256.pdf (C99-TC3)...
