Hi Johannes,
So, I could provide at least those 431 binaries for TL18/powerpc-linux.
Exhume the recently buried?
Until there is evidence of a second user, I'd rather provide them as
"custom binaries" than reinsert them into the repository.

Can you send me a link to a tarball with the binaries? --thanks, karl.
