Hum, hum.
I *am* seeing one error from the MPL regressions with cwpro8.3:
metrowerks-C++-action
c:\build\libs\mpl\test\bin\as_sequence.test\cwpro8.3\debug\runtime-link-dynamic\as_sequence.obj
### mwcc Compiler:
# In: ..\..\..\boost\mpl\is_sequence.hpp

However, it doesn't look like it's preprocessor-related.
