I prefer to not have this.  I have a PIII as well and don't see any
problems.  So this must be a compiler issue.  If gcc 2.95 generates
wrong code it cannot be used.  If (what is more likely) it generates
code which causes the loss of precision the C code must be made more
stable so that a different compiler makes no difference.

Please undo the patch and look at the code difference between 2.95 and
what ever other gcc version.
