As of Draft 12.3, the POSIX 1003.1 standard includes only getenv().
It's pretty simple to write the others; all you have to do is to
change the contents of the strings pointed to by the `environ' pointers.
This may entail using realloc() where strings get longer, and re-
assigning pointers to pointers (unsetenv()).
