The patch below should fix up the gcc issues.  But you will then get the
following one:
  udev_add.c: In function `rename_net_if':
  udev_add.c:271: structure has no member named `ifr_newname'
  udev_add.c:271: structure has no member named `ifr_newname'
  udev_add.c:271: structure has no member named `ifr_newname'
  udev_add.c:271: structure has no member named `ifr_newname'

which is a glibc issue that I don't know how to resolve.  I suggest
building using the klibc that comes with udev and see if that fixes the issue.

Hope this helps,
