Bug#533009: lib32ffi5: missing Conflicts: libc6-i386 (<= 2.9-18)

[Andreas Beckmann <debian@abeckmann.de>]

Control: found -1 3.0.9-3

Hi,

I just noticed the
  Conflicts: libc6-i386 (<= 2.9-18)
that was supposedly added in 3.0.7-2 has disappeared later on again, 
causing incorrect updates from lenny to squeeze by installing the 
library over the /usr/lib32 -> /emul/... symlink before that gets 
replaced by a directory. So the library actually ends up in /emul/... 
instead of /usr/lib32.

It's probably too late to fix this in squeeze (as most of the 
lenny->squeeze updates should have been done long ago), the package 
should still cleanup the mess it created in /emul, and ideally do this 
in wheezy (I don't think this would qualify for s-p-u):

In the postinst:

rm -f /emul/ia32-linux/usr/lib/libffi.so.5
rm -f /emul/ia32-linux/usr/lib/libffi.so.5.0.10
rmdir	/emul/ia32-linux/usr/lib \
	/emul/ia32-linux/usr \
	/emul/ia32-linux \
	/emul \
	2>/dev/null || true

should do the job.
