endianness test in md5.c

[Ulrich Mueller]

src/md5.c contains the following code:

   # include <endian.h>
   # if __BYTE_ORDER == __BIG_ENDIAN
   #  define WORDS_BIG_ENDIAN 1
   # endif

I wonder, shouldn't it just use the macro defined in m/*.h instead
(at least for the case that HAVE_CONFIG_H is defined)?
