The putenv() in the FreeBSD 7.x is made posix-conforming, that means
that the function does not make the copy of the argument string for entering
it into the environment.
As consequence, gcc/ada/env.c, __gnat_setenv() function shall not call
free() on the malloc'ed string. Otherwise, memory of the environment
strings become corrupted. In particular, bootstrap cannot proceed because
gnat tools segfaults.
