* libsupc++/eh_alloc.cc: Ensure that required macros are
defined before including gthr.h. Ensure that we get the
version of gthr.h for which we know how to provide a
configuration.
* libsupc++/eh_globals.cc: Likewise. And, bring the threading
code path into line with the current EH model. Use std, where
appropriate.
