$NetBSD: patch-bin_geotifcp.c,v 1.1 2025/05/17 21:00:16 gdt Exp $

Due to build failure on SmartOS because of a type conflict between
getopt being declared directly and the POSIX-required definition
apparently provided by stdlib.h, heavy-handedly modernize to align
with POSIX, including <unistd.h> as specified.

Not yet submitted upstream, pending bulk results.
