But the proposed Standard does address this issue.  To take your example
of <limits.h>, non-underscore stuff beyond that specified in the Standard
is not permitted to be defined by <limits.h> in a standard-conforming C
implementation.  The Standard imposes definite bounds on name space
pollution; as Dave noted, this is a unique achievement.
