Subject:     sysinfo: add Flags to Statfs_t if not already there
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=07b089176a78b3025a3c033f97cda7c12ffcae52;p=thirdparty%2Fgcc.git

sysinfo: add Flags to Statfs_t if not already there

    If there is no f_flags field in statfs_t then rename one of the
    f_spare fields, as happened in Linux kernel version 2.6.36.  This
    fixes the build on CentOS 5.11.  The CentOS kernel will hopefully not
    fill in the f_spare field, so the resulting flags will be zero.
