mingw: use COPY_ARRAY for copying array
Use the macro COPY_ARRAY to copy array elements. The result is shorter and safer, as it infers the element type automatically and does a (very) basic type compatibility check for its first two arguments. Coccinelle and contrib/coccinelle/array.cocci did not generate this conversion due to the offset of 1 at both source and destination and because the source is a const pointer; the semantic patch cautiously handles only pure pointers and array references of the same type.
