No, it does not.  I just spent 30 minutes reviewing all of the headers 
and ordering of includes, including searching to see if _SIGNAL_H_ 
include guard is used anywhere inside my codebase and it's not.

That's what brings me to the list, I am verifying if I have built gcc 
incorrectly or trying to determine other potential causes of this error.

Also, in the preprocessed output from yesterday, I verified that 
siginfo_t is being defined:

typedef __sig_atomic_t sig_atomic_t;
