There are couple of reasons why I didn't.  First, it is defined in
ansidecl.h.  There are procedures in v3 that include gthr.h.  However,
I don't believe they include ansidecl.h.  Secondly, ATTRIBUTE_UNUSED
or at least __attribute__ ((unused)) is incompatible with C++.  You
get an error message about nested functions.  There is a similar but
not identical macro in gthr-single.h.
