upc @5.2.0.1: error: invalid suffix on literal; C++11 requires a space between literal and identifier

[ryandesign (Ryan Carsten Schmidt)]

​upc doesn't build in C++11 mode:

(This log is from 10.6, on which we use clang++ 9 which defaults to C++11 mode. In time, newer clang versions will appear in Xcode, at which point this problem will affect newer systems too.)

/opt/local/var/macports/build/_opt_bblocal_var_buildworker_ports_build_ports_lang_upc/upc/work/upc-5.2.0.1/gcc/config/darwin.h:538:29: error: invalid suffix on literal; C++11 requires a space between literal and identifier [-Wreserved-user-defined-literal]
  fprintf (FILE, "\t.space "HOST_WIDE_INT_PRINT_UNSIGNED"\n", SIZE)
                            ^

You could fix this issue, which is easy, or if there are other harder-to-fix issues as well then you could add a flag to specify that an earlier C++ standard should be used.
