Thanks for the prompt > response... Re: gcompat, indeed at present it would not help at all, as all it does is add some extra stuff not already in musl's internal ABI-compat. Part of moving all the ABI-compat stuff to gcompat would be getting rid of the need for the kind of shimming you don't like, and having musl ldso do the work of loading a delegated ABI-compat shared library for executables/modules that need it.
