The intended meaning is:

  "NC_LONG" is an old name for the type "NC_INT".  "NC_INT" is the
  name we now encourage using instead.  Both names are still accepted,
  but we discourage the use of "NC_LONG", because on some platforms,
  "long" and "int" are different sizes and confusion could result.

Steve Emmerson wrote this.  I'll try to get him to provide a simpler
description or explain what is meant by "random waves", since I don't
understand it either.
