libguile/__scm.h has:
# if defined (__ia64__)
/* For IA64, emulate the setjmp API using getcontext. */
# include <signal.h>
# include <ucontext.h>
typedef struct {
ucontext_t ctx;
int fresh;
} jmp_buf;
# define setjmp(JB) \
( (JB).fresh = 1, \
getcontext (&((JB).ctx)), \
((JB).fresh ? ((JB).fresh = 0, 0) : 1) )
# define longjmp(JB,VAL) scm_ia64_longjmp (&(JB), VAL)
void scm_ia64_longjmp (jmp_buf *, int);
But, on HP-UX/IA64, <setjmp.h> has a conflicting declaration of jmp_buf.
So, on this platform, how do you use <setjmp.h> and libguile/__scm.h?
Autogen-5.9.7 fails to compile on this platform because of this:
