   Take a look at the problematic sources. Most likely some #defines are 
not set up as they should be for your platform.

   Some suggestions are:

     1. Use the '-q -d2' Boost Build optiono to find out the exact 
command line used by Boost Build when attempting to compile the source 
file causing the problems. After that you can reproduce the problem 
directly from the command line avoiding the Boost Jam/Build layers all 
together.

     2. Look at where the files reported as missing are actually located 
on your system. It could be that some #ifdef is including them when they 
should not be or may be including them from an incorrect location. If a 
different header is needed all together then see whether the correct 
header inclusion is perhaps being #ifdefed out.

     3. Once you know what file it is you are trying to compile and with 
what settings try running in only through the preprocessor so you can 
see what all the #ifdefs expanded to. You can use that to find out the 
correct includes needed to make the code compile on your platform. Once 
you have that you can back-track back to the sources and figure out 
which #ifdefs need to be modified.

    Since this is not really a Boost Build issue you might get more 
useful responses on the Boost library developer/user mailing lists.

   Hope this helps.
