Re: diff /usr/include/endian.orig.h /usr/include/endian.h > endian.h.diff

[Pedro Izecksohn <pedro dot izecksohn at gmail dot com>]

  ChangeLog entry:

2010-08-19  Pedro Izecksohn  <pedro.izecksohn@...>

	* endian.h [_BSD_SOURCE || ! _POSIX_SOURCE] (htobe16, htobe32)
	(htobe64, be16toh, be32toh, be64toh, htole16, htole32, htole64)
	(le16toh, le32toh, le64toh): Macros defined.

  I modified endian.h again:
