Comment (by ballapete):

 The pre-compiled output has:

 {{{
 # 128 "/usr/include/sys/signal.h" 3 4
 #define SIG_DFL (void (*)( ))0
 #define SIG_IGN (void (*)( ))1
 #define SIG_HOLD (void (*)( ))5
 #define SIG_ERR ((void (*)( ))-1)






 #define _MCONTEXT_T
 typedef __darwin_mcontext_t mcontext_t;




 #define _MCONTEXT64_T
 typedef __darwin_mcontext64_t mcontext64_t;
 # 160 "/usr/include/sys/signal.h" 3 4
 #define _SIGSET_T
 typedef __darwin_sigset_t sigset_t;
 # 170 "/usr/include/sys/signal.h" 3 4
 #define _UCONTEXT_T
 typedef __darwin_ucontext_t ucontext_t;




 #define _UCONTEXT64_T
 typedef __darwin_ucontext64_t ucontext64_t;
 # 186 "/usr/include/sys/signal.h" 3 4
 }}}

 The types used are not defined in this scope. I think `sys/ucontext.h`
 needs to be included that has `#include <machine/ucontext.h>` which has a
 switch:

 {{{
 #ifndef _MACHINE_UCONTEXT_H_
 #define _MACHINE_UCONTEXT_H_

 #if defined (__ppc__) || defined (__ppc64__)
 #include "ppc/ucontext.h"
 #elif defined (__i386__) || defined(__x86_64__)
 #include "i386/ucontext.h"
 #else
 #error architecture not supported
 #endif

 #endif  /* _MACHINE_UCONTEXT_H_ */
 }}}

 Could be a `configure.cppflags-append -include sys/ucontext.h` helps to
 cure the problem…
