Okay, that's great. That's exactly what I want! I want to be able to do:

    libc++ library includes > ... (rest same as C)

What I'm trying to say is precisely that this doesn't work as intended toda=
y,
because somewhere inside "rest same as C", a header is taking for granted t=
hat
libstdc++ does NOT implement a <limits.h> header. If it did, then libstdc++
would get the same issue that we are having.

Is there a reason why GCC needs to indirect through <syslimits.h> and
recursively include <limits.h>, telling it to recurse using _GCC_NEXT_LIMIT=
S_H?=
