I believe the reason _GNU_SOURCE is defined is that the code is using
the GNU "getline" function.  getline is non-standard and does not
appear to exist on Solaris 9.

Some other potential issues that gcc notices:

  - the patch introduces three sscanf calls that assume uid_t and
    gid_t are really "int".

  - if you compile on Linux with -std=c99 or -std=c89, the
    definitions of things like S_IFBLK and S_IFCHR get hidden.
    Setting _XOPEN_SOURCE will make them visible again.
