putenv.3: Originated in SysVr2; in 4.3BSD-Reno; fixed on modern systems
Fixed in:
NetBSD 6 src lib/libc/stdlib/putenv.c 1.13
FreeBSD 7 putenv(3) says so
OpenBSD 4.6 src lib/libc/stdlib/setenv.c 1.10
and is correct under current(?) MacOS as well
The current wording implies that all of 4.4BSD's descenants also carry
this bug (at least it did to me): they did until like 2009 but they're
fine now
