Here, clang reports:

xx.cc:12:7: warning: '__fastcall' calling convention is not supported for this target [-Wignored-attributes]
        int (__fastcall *volatile pFnFastcall)( int ) = lambda;
             ^
xx.cc:13:7: warning: '__stdcall' calling convention is not supported for this target [-Wignored-attributes]
        int (__stdcall *volatile pFnStdcall)( int ) = lambda;

so "supported" in the sense that it's not a syntax error.
