+The $Config{byteorder} (and corresponding BYTEORDER in config.h) was
+previously wrong in platforms if sizeof(long) was 4, but sizeof(IV)
+was 8.  The byteorder was only sizeof(long) bytes long (1234 or 4321),
+but now it is correctly sizeof(IV) bytes long, (12345678 or 87654321).
+(This problem didn't affect Windows platforms.)

+Also, $Config{byteorder} is now computed dynamically--this is more
+robust with "fat binaries" where an executable image contains binaries
+for more than one binary platform, and when cross-compiling.
