Agree. DWARF2 is bigger for single object file and GCC is slower
producing it.

Using following spu example few months ago, I measured ~15% compile 
time slowdown and big increase in size with DWARF2 compared to STABS.

"spu --language c++    --files 1 --functions 20 --function-length 10    
--lib-enums 2000 --enumerators 8    --lib-structs 1000 --fields 12    
--lib-classes 800 --methods 20    --lib-functions 10000"
