This line is related to PR 29996 and was introduced in this patch
http://gcc.gnu.org/ml/gcc-patches/2010-01/msg01147.html
I'm not sure whether removing it won't introduce some other side effects.
Maybe it should have been something like this instead?
flag_omit_frame_pointer = flag_omit_frame_pointer
&& (PREFERRED_DEBUGGING_TYPE == DWARF2_DEBUG);
I'd like to add Kaz to the CC list.
