Thanks for the quick response.  I see that floating-point bugs are frequently 
raised and closed against 323.

I'm not 100% sure it is exactly the same but 100% sure that I'm stuck.  The 
suggestion for 323 is to use -ffloat-store.  Unfortunately, for this problem it 
actually makes things worse (when used with optimisation) and makes no 
difference (when used without optimisation).  It also suggests to change the fp 
rounding mode, but the gcc info doesn't seem to mention anything for that with 
x86.

The M$ compiler has no problem with my code.  How does it do it?  How can I 
make gcc do it?  If there is no way to make gcc do it, then surely it is a bug 
or at least a missing feature?
