libnet patch - 1.0.2a header checks, SIOCGIFADDR

Hello,

Since version 1.0.2a is deprecated, but I need it to build dsniff on Solaris, I'm issuing a small patch to correct a couple of problems. This started because I got the error about SIOCGIFADDR not being found in libnet_resolve.c - which led to discovering that sys/sockio.h wasn't being recognized by the configure script because it didn't know how to run the preprocessor. Anyway, from the patch header -

  This patch modifies configure.in to correctly determine the C preprocessor   command, which it later uses to try to determine the existence of a bunch   of header files. Without this patch, and without explicitly setting the CPP
  environment variable, the configure process fails to compile the header test
  code and subsequently reports that none of the proper headers are available.
  The configure script will complete, but certain systems will have problems   (e.g., Solaris will claim it does not have sys/sockio.h, and libnet_resolve.c
  will fail on SIOCGIFADDR not being found.)

Thanks,
Russ Fink
