I'm just about to leave town.) My whole point is that generating a.out binaries and libraries didn't stop the instant that 3.0 hit the streets. To support the mixture of old binary plus new library you need a hacked ld.so. We have to supply it somehow, or simply say we don't care about certain binaries dying with obscure error messages. This XFree86-aoutlibs vs libs built on 3.x example supports my theme. I can't reconcile your naming convention (ie compat22 bits originated on a 2.2.x box) with my version (compat22 is used to support 2.2.x binaries). I'm also not afraid that a binary generated on 4.2 would have hidden defects. I'm more worried that one generated on 2.2.x would have defects we've forgotten about. If you don't mind pausing the whole argument for about 4 days, I can rejoin. :-) Stephen.
