No, because I don't care on the box I'm on. I have other cares, code
quality and size mainly, for a different target (mips).

Marc has been told many times how to do so. Many people have asked and
been told and submitted bugs on specific slowdowns that they want
addressed. Everyone seems to be able to understand this - except you.
You don't have a reputation for being particularly dense.

I'll give you the same directions other people in this thread have given
you though:

1) find a file that is compiling slower.
2) use -save-temps on the compile line and recompile it.
3) attach the resultant .i (or .ii if c++) to a bugzilla case that you
file at http://gcc.gnu.org/bugzilla/

Actually, they don't, but it's not an important argument - we get
complaints from people using machines that are much faster than mine.
