this is being caused by assignment of an initializer list to a map,
which should work.  for example
#include <map>
#include <initializer_list>
using namespace std;
int main(void) {
map<char,char> mcc = {
{'a','2'},
{'b','2'}
};
return 0;
}
will cause the same problem.
see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=51320 which I just
submitted.

does 4.6.2 not support initializer lists and other c++0x stuff yet?  I
need it desperately.  my code base already requires this in several
programs, and the DOS platform is lagging behind.
