Message: [QUOTE="August Derleth, post: 1696044"] Pop's got a point, as usual. :) If you don't pass any arguments to gcc, it compiles a C-like language called GNU C. If you pass the correct arguments, it compiles Standard C. As this is clc, we want to discuss Standard C as opposed to GNU C. You could take your ball to a gcc-specific froup and play it by your rules there, but it really isn't on-topic here due to some oddnesses of how gcc behaves by default. For example: int foo(int arg) { int bar(int gry) { int zee = 23; return gry * zee; } return bar(arg); } is a perfectly correct GNU C program, and it behaves such that bar() is only visible within foo(). bar() is a local function, something that does not exist in Standard C. I have no idea why the gcc people decided to do that, but so far the Standards committee hasn't seen fit to canonize the behavior. ;) [/QUOTE]
