Jump to case label/cross initialization

[C4me]

I am getting an error of "jump to case label" and "cross initialization" while compiling a simple test program. I started a new window project then added the following 3 lines in the message handling area. (These are the only lines I added to the entire program.)

case WM_CREATE:
int n=1;
break;

When I complile I get "jump to case label" for each of the following "case" lines (2 in the standard windows new project)
If I change the middle line to:
int n; n=1;
everything works fine. ---- What's happening?

Here is the usual info:
Windows 98SE, Dev-C++ 4.9.9.1

it won't like having a variable declaration in a case statement unless you use brackets

case WM_CREATE:
{
int n=1;
}
break;
