Including string.h is incorrect as it doesn't provide the required function prototype for strncasecmp() used in this file. Note that the missing function prototype doesn't cause a compilation error at the moment as the declaration is provided indirectly. Use strings.h to provide the declaration for strncasecmp() directly, avoiding unnecessary include dependencies and improving clarity.
