/* Despite the fact that <linux/types.h> defines sigset_t as a 32-bit type,

*
* The reason for this is that the kernel headers have a different definition
* for sigset_t depending on the value of the __KERNEL__ macro. When we cleanup
* the headers, before placing them under bionic/libc/kernel/, this macro is
* optimized as undefined, to the 32-bit definition stays.
*
* Ironically, the reason the kernel headers do this is to accomodate old
* versions of GLibc. More recent versions provide complete wrappers for the
* corresponding kernel types so don't have this problem (their sigset_t can
* always hold up to 1024 signals, independent of the platform).
