Building A Gcc 4.5 Cross-compiler For The Sharp Rom? Options

[cybersphinx]

Since gcc 2.95 is getting a bit old, and 4.5 has interesting new things like whole program link time optimization, I've though about building a gcc 4.5 cross-compiler to complement g++ 2.95 (which can't be replaced because of the ABI). The problem is, there doesn't seem to be much documentation about how to actually build a cross-compiler for the Zaurus (maybe there was more five years ago). Has anyone every tried this (probably not with 4.5, but maybe some older version)? Are there any docs on how to build any cross-compiler for the Sharp ROM, or have people always just used the premade packages?

It looks like someone has already done this with gcc 3.4... see http://prudentialscatterbrain.hp.infoseek.co.jp/

Binaries compiled with his gcc may need a static libgcc and libstdc++ which he supplies in ipks.

(He says that the files in the first table are compiled with his gcc 3.4 but don't need the additional libraries, files in the second table do).
