Subject: Fix compilation warnings

Nowadays' compilers are able to recognize memcpy and replace it
appropriately without having to tell them so through a structure
assignment. That also avoids warnings about type puning.

* utils.c (WriteCopyType): Emit memcpy call instead of type-puned
assignement.
