Mar 14, It behaves as a full dropin replacement for normal gcc based mingw toolchains (it even has tools named eg x86_64w64mingw32gcc which ends up calling clang instead, to make sure that all build systems transparently can use these tools) In addition to the regular i686 and x86_64, it also contains compilers targeting armv7 and aarch64I have an application (app) and a dynamic library/shared object (dlib), both are linked against a static library which declares a global variable (gvar) in a header file using __declspec (selectany) / __attribute__ ((weak)) By design both app and dlib should have their own copies of gvar (on MSVC and GCC I get exactly that)__declspec(property(get=GetX, put=PutX)) int x;
