I have noticed a definite loss of numerical precision going from 1.1.1 to 1.2.x under both Windows 98 and NT4 on x86 architecture. I noticed the difference when using the abcnon() function in the bootstrap package, but I think you could see the problem in any routine that involves subtracting relatively large numbers from each other. For the case I am looking at (see code below), the abcnon parameters bhat and cq should exactly equal 0.0. Version 1.1.1 did calculate these...

Good news! I received some feedback from others that they did see the problem I described using abcnon() in 1.2.0 on Windows machines but not on Linux machines. I looked into it some more and discovered that it's most likely some problem with numerical precision or round off in the pre-compiled Windows 1.2.0 version. I was able to run the abcnon function in 1.2.0 successfully in Windows by chang...
