2 errors detected in the compilation of "../../gcc/cp/class.c".
make[1]: *** [cp/class.o] Error 2

Examination reveals that a cast is missing in these an a couple of
other conditional macros to ensure that both sides return void.

Patch enclosed.

	* cp-tree.h (SET_BINFO_MARKED): Void cast to ensure both sides of
	  conditional have same type.
	(CLEAR_BINFO_MARKED): Ditto.
	(SET_BINFO_VTABLE_PATH_MARKED): Ditto.
	(CLEAR_BINFO_VTABLE_PATH_MARKED): Ditto.
