/* VC++ 4.0 is a bit annoying when it comes to precision issues (like
   claiming that "float a = 0.0;" would lead to loss of precision).  I
   don't like to see warnings from my code, but since I still want to
   keep it readable, I simply switch off a few warnings instead of adding
   the tons of casts that VC++ seem to require.  This code is compiled
   with numerous other compilers as well, so any real errors are likely
   to be catched anyway. */
