You mean, in addition to my Slackware32 i586 glibc, I have to compile my own
i686 multi-arch and place it in funky directory like /lib/i686 ?

I do not want to compile my own glibc every time my distro makes a minor update
in the package. And I do not want to hunt down problems that nobody else does.
Problems that might stem from the fact that each glibc might have minor
compilation flag differences and the programs could load a nasty i586 and i686
combinations of the provided libraries.

I want to use my distro package and to be sure that glibc would do the sane
thing.

>From the documentation I get the impression that glibc still supports i486.
I can see i486 memcpy() variant in addition to the i586 and i686 ones.

Unless you plan on dropping i486 and i586 support in a year, then please,
make it proper.
