Hi Bamvor, everybody,

I have new glibc that follows new ABI:
https://github.com/norov/glibc/tree/new-api

It's very draft and dirty, but you can try it with RFC5.
My fail list for ltplite looks like this:
pipeio_4                       FAIL       11   
abort01                        FAIL       2

rwtest03                       FAIL       2    
rwtest04                       FAIL       2    
rwtest05                       FAIL       2

Float tests are exluded, but also fail. Totally, ~40 of 787 tests
fail.
