Interest in C11 Annex K Bounds Checking Interfaces

Hi

C11 added the option of Bounds Checking versions of some common C Library
functions. There are a couple of permissive licensed implementations out
there. GIven that these are prototyped in normal header files, it would be
best if these could be incorporated somehow into newlib. At a minimum, the
prototypes for the new methods would need to be added with appropriate
conditionals. On the high end of the project, I would like to see
implementations of the functions in newlib.

We are hoping a student will tackle this for Google Summer of Code.

What are the newlib community's thoughts on this?

Thanks.

Anyone have thoughts on this? We have a student interested in this for
GSoC. First steps are to make sure it works with RTEMS.

But if merging into newlib is desired, then we need to know to plan for
that.
