extern together with an initialiser is valid so long as it is outside of
a function. In the original message it was inside one, but tcc doesn't
accept it otherwise either. I'm using tcc 0.9.24, I haven't checked if
this has since been fixed, but if not, this is a (minor) bug.

(C99 6.9.2p4 uses "extern int i3 = 3;" in an example, and 6.7.8p5
disallows it only at block scope.)
