Here is an example of the kind of compiler errors that I was seeing on 
VC9 SP1 when I ran the Chrono and Ratio regression tests:

..\libs\ratio\test\..\example\si_physics.cpp(199) : fatal error C1001: 
An internal error has occurred in the compiler.
(compiler file 'msc1.cpp', line 1411)
  To work around this problem, try simplifying or changing the program 
near the locations listed above.
Please choose the Technical Support command on the Visual C++
  Help menu, or open the Technical Support help file for more information
Internal Compiler Error in c:\Program Files\Microsoft Visual Studio 
9.0\VC\BIN\cl.exe.  You will be prompted to send an error report to 
Microsoft later.

Attached is the patch to boost/ratio/ratio.hpp that seems to prevent 
these errors.

Also attached is a patch file showing the regression tests that I had to 
comment out in the chrono test jamfile because they didn't appear to be 
in the sandbox.

I'll send more info about the WinCE 5 stuff in the near future (those 
adjustments were a little bit more extensive).

Thanks,
