Compiling the following program, with "g++ A.cpp" fails to link
with the following error message :
/tmp/ccehheUK.o:(.rodata+0x0): undefined reference to `A::x'
collect2: ld returned 1 exit status
------------------------
struct A {
static const int x = 0;
};
const int & i = A::x;
int main() {}
------------------------
It can be reproduced with g++ versions ranging from 3.2 to 4.3,
on Linux and Darwin.
Note that changing one "int" to "unsigned" makes it pass.
Is this really expected to fail ?
