New description:

 Please see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56835. It appears
 that the unnecessary patch [[source:trunk/dports/lang/gcc48/files/libstdc
 ++-configure-timespec.patch|libstdc++-configure-timespec.patch]] is
 breaking std::promise on darwin.

 The alternative fix of
 http://gcc.gnu.org/viewcvs/gcc?view=revision&revision=192335 was checked
 in to achieve the goal of using nanosleep in c++11.

 Note that the fix I checked in for gcc 4.8.0 defaults darwin to --enable-
 libstdcxx-time so neither that option nor your hack needs to be applied.
 The g++-fsf-4.8 compiler on fink doesn't fail the test case reported in
 PR56835 but has nanosleep declared in the object file...

 {{{
 % cd /sw/src/fink.build/gcc48-4.8.0-1000/darwin_objdir/x86_64-apple-
 darwin12.3.0/libstdc++-v3/src/c++11[[BR]]
 % nm thread.o | grep nanosleep[[BR]]
                  U _nanosleep[[BR]]
 }}}
