Well, as you told me that -fno-omit-frame-pointer was now implicit,
the first point seemed logical. But I agree with you on the second one.
I just didn't trigger any strange behavior using some basic SWT code,
which is fine with me for now.
May any problem happen with stack unwinding in the future, I'll know
I can rebuild the SWT DLL and test again. But considering the
impact on the DLL size, I'll stick to the official one in the mean time.

Than you very much.
