Subject: (make_path): Use proper mode_t types and macros.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=60cbbda7e63521392230e1eb7d4ae81c34784e5c;p=pspp

(make_path): Use proper mode_t types and macros.
Don't assume the traditional Unix values for mode bits.
(S_ISUID, S_ISGID, S_ISVTX, S_IRUSR, S_IRWXU): Define if not defined.
