buffer size to be in wchar_t units if wide == 1 is passed in. In
this case, also initialize the first character of the buffer to be
wide char null.
(_open_wmemstream_r): Cast buf to be (char **) to avoid warning.
* libc/stdlib/mbtowc_r.c (_mbtowc_r): Change all occurences of

names that contain equal chars.
* libc/stdlib/setenv.c: Redefine _unsetenv_r as returning int.
* libc/stdlib/setenv_r.c (_setenv_r): Return -1 and set errno to
EINVAL if name contains an equal sign. Do not remove any equal signs
from the value.

if name contains equal sign. Return -1 if no variable(s) were found
and return 0 otherwise.

n-char-sequence is omitted, still parse the ().

to support reentrancy that add a data area argument.
* libc/include/getopt.h: Add new _r routines and provide macros
