Sincecbee1bfb34endian.h is unconditionally used if available. glibc has byte order defines with two leading underscores. OpenBSD has private defines with a single leading underscore in machine/endian.h and public defines in endian.h with no underscore. The code under the endian.h block did not check if symbols were defined before equating them so '#if __BYTE_ORDER == __LITTLE_ENDIAN' would turn into '#if 0 == 0' which is always true.
