Fix compilation of Readline on mingw.org's MinGW
readline/ChangeLog
2019-12-23 Eli Zaretskii <eliz@gnu.org>
* posixstat.h (S_IRGRP, S_IWGRP, S_IXGRP, S_IROTH, S_IWOTH)
(S_IXOTH, S_IRWXG, S_IRWXO): Define if undefined, even if S_IRWXU
is defined, because non-Posix systems may defined only the user
bits.
