Hi Dear libc-help list,
I made a slight change to mtrace(mtrace.c) of glibc-2.5 and the
compile of glibc was successful. But then I found there missed some
add-ons.
The old glibc (I am using a redhat OS 5.1):
> /lib/libc-2.5.so --add-ons

The new glibc I configured with --enable-add-on without any arguments:

As can be seen, there missed following 2 add-ons:
The C stubs add-on version 2.1.2.
RT using linux kernel aio
I had searched the glibc ftp site and googled, but no luck to find
tar-balls for these 2 missed add-ons. Can someone help to suggest
where I can get those 2 add-ons?
Thanks,
Simon
