Program will not recognize that I have changed a file

I've encountered a problem where I am changing a particular c source
document and then running the associated make command in the console.
If I then run that program, it is as though the update has been
ignored.
In actuality this change I am making is for the file tcpdump.c for the
program tcpdump.
I am changing a simple print statement that I am sure will be
executed:

Something like
        fprintf(stderr, "%d packets received by
filter\n",stat.ps_recv);

** is changed to **

        fprintf(stderr, "%d packets received by filter BLAH \n",
stat.ps_recv);

I don't feel that the particular program is the source of my problem.
I have done the basic commands to set it up (./configure, make, make
install) and it is running fine. Concerning my update, I am sure that
tcpdump.c is actually being changed and the giving the make command
again acts as though it recognizes a change of a file, and running
make once again will reply that all the created .o files are up to
date. Does anybody know of what could be keeping my addition of "BLAH"
from being printed? I am not very experienced with c so I figure I
must be overlooking something involving compilation.
. I am using SuSE linux and the makefile calls the gcc compiler.
