Dear All,
As per my understanding with respect to Autoconf, I've made the following
changes and still observed the same fatal errors with less number.

Before the reconfiguration(autoreconf), I observed around 12 fatal errors
which have been reduced to 2 errors only. Please correct me if I'm going in
the wrong direction and help me to resolve this issue!
*Note:* The my_macros.h file is available in the
/home/anand/workspace/modules/snmp/net-snmp-5.8.pre2/../../inc directory
and in this scenario I did not make use of the ./configure option
--with-cflags.
Thanks in advance!
