Which version of Boost.Build? I ask because it seems you are using Boost 
1.33.1 below.

Yea, that would be the Redhat packagers. If you build+install manually 
they would end up in the same place as you observe for Cygwin.

Add:

   <target-os>cygwin:<include>/usr/include/boost-1_33_1

To your project targets, either as a project requirement or to selected 
targets as needed. I'm assuming you are using the latest Boost.Build v2 
code for this. If you aren't please answer my first question and we can 
give you a more precise answer.
