Avoiding floating point problems on Pentium Xeon platform w/ GCC 3.2

["Kleinbussink, Erik" <erik dot kleinbussink at lmco dot com>]

I am porting an engineering application which uses double precision
calculations from its original platform (Alpha-based Tru64 UNIX) to Intel
Xeon-based linux. I have run into problems with floating point handling.

Below is one of the situations I ran into.
	int main()
	{
	        double d1, d2;
	        int i1, i2;

	        d1 = 0.04;
	        i1 = 100;
	        i2 = 100;

	        d2 = i1 / d1;
	        i1 = d2; 
	        i2 = i2 / d1;

	        printf("%d %d\n", i1, i2);
	        return 0;
	}

On Alpha, the above application results in "2500 2500", but on Intel Xeon,
it results in "2500 2499".

I have been reading gcc documentation, and it sounds like this is a known
complaint with x86 series chips. I am interested in help on what the best
course of action is? 
	- Review / Rework all source code manually (Very painful)
	- Neat compiler flags/tricks which make this problem not a
problem...
