> This is an adaptation of the IBM XL compiler's -qstatsym option, which is meant to generate symbol table entries for static variables. An artifact of that compiler is that static variables are often not discarded even when unused.

Oh, I see; the compiler actually doesn't guarantee that the variables are preserved, it just ends up preserving them by accident because it's bad at optimizing global variables?

Do you have any idea how widespread this is?
