void f2(long foo, ...) {/*empty*/}
f2(-1, -2); //-1 correct, -2 becomes 0x00000000FFFFFFFE
You are passing -2 as an (32bit) int and not as a (64bit) long to a var-args
function so this is not a bug unless you can prove that this is incorrect by
the ABI. If you are trying to port to x86_64-cygwin and this is demanded by
the ABI, you should change the internals of GCC for that ABI but the elf one as
far as I know says it is past as an int and not as a long.
