The original recommendation that I posted was for the Alpha and any
other architectures that may have problems with the current "stable"
gcc. On the Alpha, at least, I have never had a problem with an
egcs-compiled kernel (I hear x86 kernels have had problems if compiled
by egcs, but I believe that's been resolved now).

Hmm...the only problem is that libstdc++-dev conflicts with libg++-dev,
which could cause a problem if both are needed. Unless a decision is
reached as to which should be the default compiler (at least on the
Alpha and maybe on other arch's too), then this could end up being a
very real immediate problem.

I agree with this and would recommend it anyway (since we now have a
choice of sorts). I don't want to see people have to install and remove
compilers and dev packages just to compile a package or two, however.
BTW, the only reason I started this on private was because it related to
the release guidelines and goals :)
