Bug 20456 – linker can't find the C function wmemove when -mscrtlib=msvcrt

The following program fails to link. ``` import core.stdc.wchar_; int main() { wchar_t[10] a = void; wchar_t[10] b = void; wmemmove(a.ptr, b.ptr, 10); return 0; } ``` compiled with: dmd test.d -m64 -mscrtlib=msvcrt The equivalent C program succeds. ``` #include <wchar.h> int main() { wchar_t a[10]; wchar_t b[10]; wmemmove(a,b,10); return 0; } ``` compiled with: cl test.c /MD
