Rockbox is usually compiled with gcc 4.4.4 and binutils 2.20.1 (on ARM). In the past when we've had to change gcc versions we encountered quite a few problems due to subtle differences in how different gcc versions work. If possible, I would use gcc 4.4.4. It will save you having to troubleshoot gcc bugs.
Oh yes indeed sorry for having forgotten that. I'm using gcc 4.3.2

And yes for optimizations. You need to place that in the line where options like "-W -Wall" etc are

EDIT: I think it will be better to keep the usual /.rockbox folder. So my idea is:
- create a new rom (with some other fixes too possibly) with a folder at root "/.rockbox"
- in the script that launches rockbox, make something like "mount <CWD> /.rockbox [don't remember exactly the command yet ]

In this way you should be able to run rockbox from any directory as positive cons. What do you think?

EDIT2: next step will be to introduce power management. I have necessary informations, but I'm lost in RB code, so help is needed

EDIT3: absolutely. Adding the optimization options worked maybe. I get 13-14 fps in pictureflow instead of 11 (not so much indeed, but may be helpful with battery + random clicking)

EDIT_LAST: okay in this edit I remind we need to activate in some way the specific ARM optimizations coded in RB
Check out my modded firmware both for YP-R0 and YP-R1!!!
