Comment (by anonymous):

 this change is not yet in 1.52.0.



 since i don't use glibc (first check, which would use endian.h), my armel
 device was not detected correctly.

 modern gcc's (iirc 4.4+) provide {{{__BYTE_ORDER__}}}
 so the code should do the following:

 {{{
 #if defined(__GNUC__) && defined(__BYTE_ORDER__)
 # if __BYTE_ORDER__ == __LITTLE_ENDIAN__
 ...
 #elif defined(__GLIBC__)
 #include <endian.h>
 #else
 ... eternally incomplete cpu-specific ifdef hell here
 #endif

 }}}
