Hmm. Looks to me like the programmer probably tried to silence
the warning resulting from the lack of inclusion of stdio.h by
adding (void) then..
Any idea where one would plop in a #include to have
<DPS/dpsclient.h> included in all the files that emit warnings
because it isn't there?
Thanks Keith,
