[patch] do not use trunc()

["Steve M. Robbins" <steven.robbins@xxxxxxxxxxxx>]

Hi,

I maintain OpenInventor for Debian.  On some combination of
hardware and compiler, GCC complained about the function trunc():

 ../../lib/database/src/sb/SbTime.c++:71: new declaration `int trunc(double)'
 /usr/include/bits/mathcalls.h:291: ambiguates old declaration `double 
    trunc(double)'

This is only used in one place in the sources, and is easily 
worked around by the following patch.
