 That's not been my experience.  For example, Qemu won't compile
 with gcc-4, yet doesn't have gcc-3 as a dependancy.

 qemu is just a meta-ebuild, in ~x86 qemu-softmmu-0.9.0-r1:
 pkg_setup() {

  die gcc 4 cannot build q
 fi

My mistake.  I was thinking of OpenEmbedded.  It uses a build
system very similar to portage, and that's where I recently ran
into problems with Qemu being built using gcc 3.

Just mask it. Everything will be fine.

Hey Walter just a little aside in case.

I discovered that ksh93 depends on version gcc-3* in a brand new
install where portage just installed gcc-4* apparently by default.

Its a very new and pared down system... but I like ksh93 and was sorry
to see it needs gcc-3*... I doubt I'll miss it enough to start diddling
around with changing versions of gcc.  

I do have lots of script that won't run in bash without some changing.

So if you are a ksh93 person... maybe you should look into it.

There is at least one package (e.g. Qemu) that won't build with
gcc 4.x (at least that's been my experience).
