[Boost-build] Building cygwin and/or mingw dll's

Dear Boost.Build gurus,

I would like to build a DLL using cygwin gcc and export symbols using a 
.def file. I have put "<def-file>exports.def" in the requirements for 
the target. I have two questions:

1) When I build the DLL using Boost.Build v2, everything works perfectly 
if I use the msvc toolset but it appears that when I use the gcc 
toolset, the file "exports.def" is never used, and the symbols don't get 
exported properly. Is there an easy way to fix this?

2) How can I put in conditional requirements distinguishing between:
- msvc
- gcc with cygwin (or mingw)
- gcc on a different platform
