/home/jaswinder/jaswinder-git/linux-2.6-tip/usr/include/mtd/jffs2-user.h:20: extern's make no sense in userspace

--
include/mtd/jffs2-user.h:

extern int target_endian;

#define t16(x) ({ uint16_t __b = (x); (target_endian==__BYTE_ORDER)?__b:bswap_16(__b); })
#define t32(x) ({ uint32_t __b = (x); (target_endian==__BYTE_ORDER)?__b:bswap_32(__b); })
--

In above case extern is OK or not ?

Do we have some better alternative.

Thanks
