I would very much like to use gcc-3.3 for compiling everything,
including the sh-4 kernel.  But I guess I will plan on using gcc-3.2.3
for that for now, after reading your message!

As for gcc-3.4 ... since earlier compilers had -mno-implicit-fp,
couldn't you consider this a bugfix rather than a feature? :-)
