Hi, I am handling some project which mixes managed and unmanaged C++ code. With boost 1.33 I’m hitting problems with the header is_mem_fun_pointer_tester.hpp. There are warnings popping up due to the use of __fastcall calling convertion in boost and its incompatible with compiling some of our code with the /clr flag turned on. Managed C++ is incompatible with the __fastcall calling convention because what it does is it preloads certain registers with the function parameters but for /clr compilation it is compiling to MSIL so this cannot be done and upon encountering any __fastcall the Managed C++ compiler will change it to __stdcall. Does anyone know the implications of disabling these warnings and whether it is safe to do that? I did not get these warnings with the previous versions of boost though. Thanks and regards, Chu-Ming
