Today I've just had kgcc64 pop up as a new package to emerge on sparc64. What's the rationale behind the change to kgcc64 from gcc-sparc64?

There are a couple of architectures on Gentoo that have a 32-bit userland, but need a 64-bit kernel compiler. kgcc64 is an attempt to provide one package for all of those architectures rather than the gcc-<arch> packages that exist now. The way we migrated over to this caused the issue you are seeing.

gcc-sparc64 is blocking kgcc64. Is it OK to unmerge gcc-sparc64 then emerge kgcc64?

Calculating world dependencies... done!
[blocks B ] sys-devel/gcc-sparc64 (is blocking sys-devel/kgcc64-3.4.6)
[ebuild N ] sys-devel/kgcc64-3.4.6 USE="-multislot -test" 0 kB

Yes, it's ok to unmerge gcc-sparc64 and merge kgcc64 instead.
As weeve said some architectures had the gcc-"arch"64 compiler and it was decided that we'd go into a unified kgcc64 so as to maintain the compiler easily and avoid duplicate work.

is there anything else to this "migration"? a simple 'emerge --unmerge gcc-sparc64 && emerge sys-devel/kgcc64' will be good enough on most systems?

That worked for me and I didn't have to recompile anything else.

JR :D

Yup, the migration path is unmerging gcc-sparc64 and emerging kgcc64

Interesting. Now when I try to compile the kernel (both 2.6.19-r5 and 2.6.20) I get:

Hmmm did you env-update and source /etc/profile after it was done?
Also what does gcc-config -l say?
