    lib/libc/stdlib      getenv.3 getenv.c putenv.c setenv.c 
  Log:
  Make putenv() fully conforms to Open Group specs Issue 6
  (also IEEE Std 1003.1-2001)
  
  The specs explicitly says that altering passed string
  should change the environment, i.e. putenv() directly puts its arg
  into environment (unlike setenv() which just copies it there).
  It means that putenv() can't be implemented via setenv()
  (like we have before) at all. Putenv() value lives (allows modifying)
  up to the next putenv() or setenv() call.
