ummm.... why is there a limits.h file now?

[Benjamin Kosnik]

I was looking through bits/c++config, and saw:

// And any CPU-specific definitions.
#include <bits/limits.h>

Here's what's wrong with this:

1) limits.h is a "C" compatibility header. Use something besides this,
   say cpu_limits.h. (No point in confusing things, especially since
   glibc has a bits subdir as well.)

2) there should be no includes in c++config, if possible. This should
   just be included in bits/std_limits.h:

#include <bits/c++config.h>
#include <bits/cpu_limits.h>

Thoughts?
