/* 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. */
