gcc - Static local C variables are followed by a number in assembler code. Is that number random? -

-

i wonder if number follows local static variable name in assembler random or if there meaning.
compiled sample c source gcc v. 4.7.2 in debian wheezy; assembler listing shows row containing: 

.comm   i.1705,4,4

where 1705 come from? thank in advance.

here source: 

int main() { static int i=0; return i; }

it counter of identifiers encountered during compilation. if put declaration behind, gives me next number. if put another, non-static, object in between difference 2.
