Thnaks for the report.  That would be these tests below.  They are a 
known problem
with gcl under windows.  Unfortunately the testsuite doesn't allow us to 
make
known errors conditional on platform and lisp.

Interestingly, I don't see them with my experimental windows build of 
CVS maxima
using gcl/gcc-4.6.2. 
(http://www.math.utexas.edu/pipermail/maxima/2012/027475.html)
Another reason to test this new build.

Running tests in rtest16:
********************** Problem 185 ***************
Input:
        60
       2   - 1
float(-------) - 1
          60
         2


Result:
- 1.1102230246251565E-16

This differed from the expected result:
0.0

********************** Problem 186 ***************
Input:
        1000
       2     - 1
float(---------) - 1
          1000
         2


Result:
- 1.1102230246251565E-16

This differed from the expected result:
0.0
