That would be interesting. In theory, we should be able to mimic the
internal glibc .h files. The devil is in the detail.

My first order problem is that I have never seen the procedure for running
glibc tests against a newlib based toolset for any newlib target -- embedded,
Cygwin, or Linux.

Heck.. as I posted earlier, I don't even know what to do to run the
tests inside the newlib tree. :(
