grep reveals that this is a macro sitting in byteswap.h.  Do you have
this file in your compiler's include path?  Installing glibc-devel
should get you this file if you are on Linux, as per Google.

$ cd /usr/include
$ grep -r "bswap_64" *
bits/byteswap.h:#  define __bswap_64(x) \
bits/byteswap.h:#  define __bswap_64(x) \
byteswap.h:# define bswap_64(x) __bswap_64 (x)
$
