Are you aware of the scale of this issue with eCos CVS and GCC 4.6.2?If it could be some measure, the compilation of eCos library for the /default/ template (target K60N512) raises 11 warnings, all seem to be the same type: warning: variable ‘<varname>’ set but not used [-Wunused-but-set-variable] Some cases are unused variables indeed, but of some the usage is "hidden" (within asm() or macro).Try redboot (on a target including flash and network). There's a lot more there.
Feel free to ask.There are a few patches that were applied to current toolchain sources:

It would be useful to review these and determine which are still relevant.I have implemented them in my build (for ARM only). They seem to fit with the new code but regarding relevancy it probably requires more analysis and better knowledge of GCC intrinsics than mine.
