"left shift count" warning while compiling

[Alvaro Figueroa <fede2@fuerzag.ulatina.ac.cr>]

I'm getting lots of this:

/usr/include/linux/byteorder/swab.h: In function `__fswab64':
/usr/include/linux/byteorder/swab.h:165: warning: left shift count >=
width of type

Could this be safely ignored? I'm on a sparc64 box.
