Thanks Andrew. That looks like the problem. After spending over an hour
wading through the windows build infrastructure, I finally got enough of
an idea of what was going on so that I could test the change...

The following command line

    ..\bin\exec -d c:\build\stdcxx\trunk\examples spell.exe radix.exe
tele.exe

Produces this output with Farid's change,

    NAME         STATUS WARN ASSERTS FAILED PERCNT    USER     SYS
REAL
    spell.exe      DIFF    0                         0.015   0.000
0.000
    radix.exe      DIFF    0                         0.015   0.015
0.000
    tele.exe       DIFF    0                         0.015   0.000
0.000

And produces this after removing it and rebuilding the exec utility.

    NAME         STATUS WARN ASSERTS FAILED PERCNT    USER     SYS
REAL
    spell.exe         0    0                         0.015   0.000
0.000
    radix.exe         0    0                         0.015   0.000
0.000
    tele.exe          0    0                         0.015   0.000
0.000

I'll be committing a fix in a few seconds.
