	Because HAVE_UNISTD_H is not in src/lib/libz/Makefile.
	I think original libz was using configure (GNU autoconf).
	Is it correct?

	I think it is better not defining it in zconf.h, as the symbol
	will become visible to third-party user code and may affect their
	compilation (though I believe it is rare to get bad sideeffect,
	I prefer not defining it for safety).
