Re: Problems with packages on a netbsd-6 sparc

I had a look: as Eduardo suggested, the memcpy is inlined as a struct
copy. The code is lying (by using bogus casts), and the compiler is
correct in its optimization.

This patch avoids the lie about the memcpy() args to the compiler,
but I have not tested it further:
