Can you (or someone else) look at the w32 system headers and see how
struct passwd is defined there?  I looked at two implementations
(DJGPP and glibc on Debian GNU/Linux), and they both define pw_dir and
pw_shell as `char *'.  So using strcpy here might mean a disaster, as
no memory could have been allocated for them; I'd use strdup instead.
