Specifically on ARM, going further makes things rather useless especially for build testing: with gcc-4.2, we lose support for ARMv7, EABI, and effectively ARMv6 (as it relies on EABI for building reliably). Also, the number of false-positive build warnings is so high that it is useless for finding actual bugs from the warnings.
If you start with that activity now, there's indeed a massive amount of warnings to look into. However, I've been build testing various configs with m68k-linux-gnu-gcc-4.1.2 and looking at the compiler warnings for years, so I only have to look at new warnings.
What's the reason for sticking with gcc-4.1? Does this actually work better for you than a more recent version, or is it just whatever you installed when you started the build testing?
