fix(mingw): get rid of MinGW's stupid interface macro definition

    
In [1], they defined interface to struct although the code is not
Object-C or Object-C++. It's stupid and violate C/C++ standard: all
identifiers used by compiler or standard library should either be
a keyword, or be start with an underline plus a uppercase latter or two
underline to avoid conflict with user defined identifiers.
