Re: [PATCH v0 0/2] Add C23 stdbit.h functions

Thanks. I finally aligned all the autotools versions with your changes.

It all built for me to target sparc-rtems7.

You mentioned a problem compiling these earlier. What target was that? I
think all the
XXX_WIDTH constants used are in limits.h.

And is there any organization behind ELIX and ELIX_LEVEL anymore? Is 3
everything or some restricted subset. We would like them on RTEMS and I
assume we would be a more restricted profile since we are single process.

Thanks.
