[bug-inetutils] iruserok missing in OpenSolaris

[Mats Andersson]

Dear all,

not too long ago "libinetutils.a" implemented "iruserok()",
but the code has been removed. This function is still in use by

     src/rlogind.c
     src/rshd.c

but the project now relies on the availability of this function
within the Libc on a given system.

However, the Libc implementation of OpenSolaris/NexentaCore
does not provide "iruserok()", only "ruserok()". Do we want
to reintroduce some sort of wrapper?

Best regards,
  Mats
