OK, let's be blunt.

99% of applications and libraries (that I use regularly) compiled with GCC >=
4.3 have bigger (binary code) sizes and lower speed. You can _easily_ check it
on your own. And I cannot come up with a really simple testcase because a new
compilation infrastructure introduced in GCC 4.3 made everything not so
brilliant.

The last but not the least - is that I'm not a developer at all, I have no
knowledge of assembler, thus I have no ability to analyze code produced by
different GCC versions. All I see is the end result and it's far from being
remarkable.

It seems like GCC developers are busy implementing new features forgetting
about the core mission of any compiler - creating the most efficient code for
all supported architectures. I'm closing this bug since I feel no one will step
up to even confirm it.
