As usual while waiting for the next release - don't forget to check the nightly builds in the forum.

These are passed to the linker I think, when doing LTO.Generally someone should add a capability to show comboboxes here and probably specify a way to specify options which are compiler and linker or even if they depend on other options.
Problem is that -Wl,warp=symbol does not emitted properly by C::B.
