There's no sigcontext.h in libc5.
It doesn't compile on IRIX 6.2 either, for the same reason.

There's no sigcontext.h in libc5.
glibc-2's sigcontext.h is basically just:
#define sigcontext_struct sigcontext
#include <asm/sigcontext.h>
The structure is called `struct sigcontext' on 2.1.*, and `struct
sigcontext_struct' on 2.0.*.
