Something went wrong when you configured gcc.

You should see this in libcpp/config.h:

#define HAVE_LIMITS_H 1

If you don't have this, you need to look at config.log to find out why.
It may be that you need to configure again with a clean tree.
Make very sure that you aren't building in the srcdir.
