I've been playing with building and using the libc6-i686 package recently, mainly to help track down a Red Hat bug.
A few little problems I noticed: - I think the .postinst is really supposed to be the .postrm - libc6-i686 contains /lib/ld-linux.so.2, which conflicts with libc6. Simply removing this file from the packge make it work. - The default CFLAGS is "-O99 -fomit-frame-pointer -D__USE_STRING_INLINES". I'm not sure if this is upstream's idea of a joke or what, but it causes massive instability in pthreads. "-O2" works fine. "-O3" causes subtle problems that I've been seeing in Red Hat 8.0's package. (Corruption in pthread's data structures.) After fixing those, it seems to be rather stable. I wish I could say that I see massive performance improvements, but I don't. dave...
