// bug 12178901 - linkage of global const objects

// What is the `linkage' of const objects in C++?

// GCC generates code for the following such that `ci' has
// extern linkage, and such that its initial value is 99.

// G++ 1.36.1 however optimizes this declaration into nothing.
// Thus, if some other file contained `extern const int ci;'
// that other file would fail to link.

const int ci = 99;
