Ivan Maidanski 4d24d7429f Remove redundant checking of CPPCHECK macro in gc_cpp.h 
(fix of commit 5e51e8d)

Issue #229 (bdwgc).

* include/gc_cpp.h [(_MSC_VER || __DMC__ || (__CYGWIN32__ || __CYGWIN__
|| __MINGW32__) && !GC_BUILD && !GC_NOT_DLL) && __cplusplus>201103L
&& GC_OPERATOR_NEW_ARRAY] (operator delete[](void*,size_t)): Define
even in case of CPPCHECK.
