[issue3813] cannot lanch python.exe via symbolic link if HAVE_BROKEN_MBSTOWCS

[Amaury Forgeot d'Arc]

http://man.he.net/man3/readlink says: "Conforming applications should
not assume that the returned contents of the symbolic link are
null-terminated"

cygwin is not broken, but very (too much?) conforming in this case ;-)

I think your second patch is the correct one, just keep the "return
(int)r1;" because the return value is stored in a "linklen" variable.
