See <http://www.indiegigs.co.uk:8010/linux_ppc/builds/111/step-yhc/0>
errors at the end from ghc-6.6.20070415 on the same "binary" library for
the Yhc buildbot. I don't know if this error is a regression versus 6.6
and I can't figure out how to reproduce it outside my Yhc-buildbot (I
tried building the library with a wrapper shell script ghc-6.6.20070415
"$@" -O0 -fasm, and it succeeded building the Binary library without any
warnings OR errors, so I don't know what's going on...)
(I'm not entirely sure, since Ubuntu 7.04 packagers build my 6.6, so maybe
they did something to it that made it work better -- made it
unregisterised, at least, and unable to use ghci or produce -fasm output.
But the ghc-6.6.20070415 warning messages above, from the .hc look to be
-fvia-C, and produced by the C compiler before any mangler starts on the
produced assembly...)
