While looking around to see where to insert strlcpy(), I couldn't help
noticing that port/strdup.c has its very own header file,
include/strdup.h. AFAICS this is utterly redundant given that we have
#ifndef HAVE_STRDUP
extern char *strdup(char const *);
#endif
in port.h. Can anyone see a reason not to remove the extra header?
