One way of achieving this is to do:
#define getcontext hide_getcontext
#include <ucontext.h>
#undef getcontext
Andreas suggested another method. Both have their ups and downs.

This doesn't sound right. There were no member-name changes "struct
sigcontext". I just checked the current libc CVS tree and it has:
struct sigcontext
{
:
unsigned long int sc_ar_bsp; /* backing store pointer */
So I don't know why this isn't working for you. What distro are you
using?
