 Based on the comment in raise.c, I don't think the fix is
 correct although there probably does need to be a stub for
 _Unwind_SjLj_RaiseException in raise.c.  We also need to fix the
 call issued from a-except.adb.  This is actually what caused the
 link failure in the PR.  raise.o isn't in libgnat.a.
 
 I hacked a-except.adb and raise.c use to use _Unwind_SjLj_RaiseException
 but not being familiar with ada I'm not sure how to conditionalize the ada
 code.  I'm also not set up to test the exception support in it.
 
 I suspect the same problem affects the hpux ports which use sjlj
 exceptions by default.
