 POSIX does not specify whether @code{setjmp} saves the signal mask in the
 @code{jmp_buf}.  It does on BSD platforms, and on glibc platforms when
address@hidden is defined; in this case @code{setjmp} behaves like
address@hidden(.,1)}, and functions @code{_setjmp} and @code{_longjmp} are
-available that don't save or restore the signal mask.  On System V platforms
-(excluding HP-UX), and on glibc platforms by default, @code{setjmp} doesn't
-save the signal mask.
