Thanks for the information. Just to clarify, what exactly do you mean 
by "only really suitable for use with cygwin builds?" Do you mean only 
suitable for building using the gcc that comes with cygwin? Does the 
build.bat-based bjam delegate compiler executions to a windows shell 
even if bjam is executed from cygwin? I just want to make sure that I 
understand the nature of the issue.

One last question: I'm not very familiar with cygwin so please bear 
with me. Can I execute build.bat from cygwin (specifically, from 
run_tests.sh)?

Thanks,
