OK.  'Unimplemented' should mean that there is no known obstacle to
the feature external to GCL, such as a missing libdl or some such, and
that we have not tried to make it work and failed.  Otherwise,
'broken' is more appropriate I think.

I am hopinh this is a 'low hanging fruit' -- the following should be
in config.h:

#ifdef IN_GBC
#undef MPROTECT_ACTION_FLAGS
#define MPROTECT_ACTION_FLAGS SA_RESTART|SA_SIGINFO
#define GET_FAULT_ADDR(sig,code,sv,a) \
 ((siginfo_t *)code)->si_addr
#endif

#define ADDITIONAL_FEATURES \
                     ADD_FEATURE("SUN"); \
                     ADD_FEATURE("SPARC")

#define SGC

Great!
