[Bug target/41095] 4x bigger object when compiled with -O3 option

[ami_stuff at o2 dot pl]

------- Comment #10 from ami_stuff at o2 dot pl  2010-01-23 03:26 -------
Looks like -mnobitfield option increases object's size more than 100%. I don't
know if so big file size increase is correct. Another problem can be noticed
with GCC 4.4.2 which generated 45% bigger object than the rest of the 4.x
compilers, so maybe some internal settings should be tweaked for this branch.
