Global Definition Vs Global Declaration

Hmm strange. I am not sure if I am doing this wrong. Here's the sample
code that I am running this on:

// Global decls
static int staticint;
extern int extint;
int globalint;

int main(void)
{
    int a[10],i, *p;
    globalint=0;
    return 1;
}

And here is the output from the plugin code:

Glob var: staticint   decl_external:0 tree_static:1 complete:1 common: 0
Glob var: extint      decl_external:1 tree_static:0 complete:1 common: 1
Glob var: globalint decl_external:1 tree_static:0 complete:1 common: 1

decl_external is set for both globalint and extint. I am trying this
with 4.6.2 source.

Thanks for your time. Appreciate it.
