Hey, we have a serious issue with C++! Sorry, I've just realized. See below:

$ cat cpp_enum.cpp
enum Enum {A=0,B=1};
void foo(Enum e){}
void test() {foo(A|B);}

$ g++ cpp_enum.cpp
cpp_enum.cpp: In function ‘void test()’:
cpp_enum.cpp:3: error: invalid conversion from ‘int’ to ‘Enum’
cpp_enum.cpp:3: error:   initializing argument 1 of ‘void foo(Enum)’

We have two options:

1) Change the argument of DMDASetBoundaryType to "int", do the same
with the 'wrap' slot in DM_DA structure.

2) Change to the cleaner API I've suggested in my previous mail (with
OK from Barry).
