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.
