*** The GNU C library is currently not available for this platform.

*** So far nobody cared to port it and if there is no volunteer it

*** might never happen.  So, if you have interest to see glibc on

*** this platform visit

*** http://www.gnu.org/software/libc/porting.html

*** and join the group of porters

byteswap.h   是glibc库的文件。
