/*
* This file is derived from RFC 3492bis written by Adam M. Costello,
* downloaded from http://www.nicemice.net/idn/punycode-spec.gz on
* 2015-03-02 with SHA1 a966a8017f6be579d74a50a226accc7607c40133, a
* copy of which is stored in the GNU Libidn version controlled
* repository under doc/specification/punycode-spec.gz.
*
* The changes compared to Adam's file include: re-indentation, adding
* the license boilerplate and this comment, adding the #ifndef
* PUNYCODE_H and IDNAPI blocks, changing the return code of
* punycode_encode and punycode_decode from enum to int, simplifying
* the definition of punycode_uint by #include'ing idn-int.h and using
* uint32_t instead of limit.h-based code, adding Punycode_status and
* punycode_strerror, adding 'extern IDNAPI' declarations to function
* prototypes, and mentioning variable names in function prototypes.
*
* Adam's file contains the following:
*
* punycode-sample.c 2.0.0 (2004-Mar-21-Sun)
* http://www.nicemice.net/idn/
* Adam M. Costello
* http://www.nicemice.net/amc/
*
* This is ANSI C code (C89) implementing Punycode 1.0.x.
