I keep changing between compiler versions all the time just so I can ensure builds with older compilers keep working until we officially deciede to drop support for them. So the minimum compiler version for 32-bit MIPS kernels is gcc 3.2 and for 64-bit kernel gcc 3.3. But for sake of sanity and productivity I definately don't mind dumping support for gcc < 4.0 or maybe even 4.1. And while we're at it, let's deprecate ancient binutils version as well. A minimum version of 2.17 would be nice as I could get rid of lads of .word sillyness which is needed to support older binutils. Ralf
